In 1987, following a number of years as part of a
new romantic and
punk covers band called G Konrad, Jonas Berggren formed a band with two friends, Johnny Lindén and Niklas Tränk, for a school project; his sisters Malin, called "Linn", and Jenny, joined as singers. The new band went through several names:
Kalinin Prospect after an avenue in Moscow; CAD (Computer-Aided Disco); and Tech-Noir, French for black technology, after a
nightclub in the film
 They toured the clubs of Sweden with self-written material,
techno inspired by the likes of
The KLF and
Snap!. Johnny left the group in 1989, and Niklas made his departure known by failing to appear at a performance, instead attending a
Rolling Stones concert on the other side of town.
 Jonas asked his friend Ulf Ekberg to stand in for Niklas. The new quartet sought a new name to make a fresh start. Linn was reported to have said: "No one could pronounce the name of the group and nobody could remember it." They settled on Ace of Base after Ulf was inspired by the music video for the
Motörhead song "
Ace of Spades".
However, the band continued to struggle to gain recognition, partly due to the preference of
heavy metal over
techno in their hometown, according to singer Jenny.
 In 1991 they responded to a newspaper ad by producer John Ballard, who was looking for new talent. He was somewhat unsure about their potential, but did pass them on to Klas Lunding at Telegram Records, who helped them record an early demo for the song "
Wheel of Fortune" in their newly renovated studio. A Jamaican reggae band resided in a studio next door to theirs, leading to a collaboration of ideas.
 This resulted in a fusion of reggae with pop which became the band's trademark sound. "Wheel of Fortune" did not convince Telegram to sign the band, and other labels in Sweden still showed no sign of interest. The demo was eventually sold for a small price to the independent
Danish label Mega Records in March 1992.
 "Wheel of Fortune" was re-recorded and released as a single in Denmark in May, but it failed to chart. A small-budget music video was shot and directed in a small studio by Viking Nielsson
 and in September, after two failures, the single finally charted.
International success and Happy Nation/The Sign (1993–94)
Ace of Base was influenced by
"Another Mother" to write and compose "All That She Wants".
While "Wheel of Fortune" was a modest success, a different song led Ace of Base to take off
internationally. After hearing
Kayo's "Another Mother", a top 20 hit in Sweden, the band decided that it was exactly the sound they wanted to create.
 They contacted the song's producer,
Denniz PoP, and sent him a demo of a song they called "Mr Ace". The tape got stuck in the cassette tape player in his car, so he listened to it over and over again, which helped him decide to produce the song.
 The song became "
All That She Wants", and upon its release in October 1992, it quickly climbed to No. 1 on the Danish chart while the previous single was still sitting at No. 2. Keen rushed out an
LP for the Christmas market,
Mega Records pressed the band for an album and it was hastily recorded, mixed and released within a few weeks.
Happy Nation, was an instant hit in
Denmark, and its success prompted interest elsewhere in Europe. A Pan-European license was signed with
Universal Music), but they were turned down by the American division. Within a few months, "All That She Wants" had reached No. 3 in
Sweden and had spent eight weeks at No. 1 in Germany. In various European countries, "
Happy Nation" and "
Waiting For Magic" were released as further singles following the release of the album.
In May, "All That She Wants" continued to be a hit all around the world and topped the chart for three weeks in the United Kingdom. In November 1993 it repeated the feat in Australia, where it also peaked at No. 1 for three weeks. However, despite
Mega Records's hard efforts to secure a distribution deal in the United States, the response was always the same: "This band will never work in the States." Eventually, however,
Clive Davis, founder of
Arista Records, thought otherwise, and by the end of 1993 "All That She Wants" had made its way to No. 2 on the
Billboard Hot 100 in the United States.
In order to freshen up the album for American release, Davis insisted that some new tracks be recorded, including "
The Sign", which became the new title track for the album and the second American single. It was even more successful than the first, spending six weeks at No. 1 and becoming the best-selling single of 1994. It was also a major hit in Europe, peaking at No. 2 in the UK and Sweden and at No. 1 in Germany; in Australia, "The Sign" spent the entire month of May in the No. 1 position, becoming the country's fifth highest-selling single of 1994.
Due to fears of imports from the United States, the original European album was re-released with new tracks under the name
Happy Nation (US Version). This was the first version of the album to chart in Australia, in April 1994. Collectively, the different versions of the album reached the No. 1 position in at least 14 countries, and sold more than 23 million copies worldwide.
Two more singles were released: "
Don't Turn Around" and "
Living in Danger". The former was originally recorded by
Tina Turner, as the
b-side of her single "
Typical Male". Davis suggested that the band record the song and it was yet another worldwide hit. The latter was a moderate chart hit in most countries where it was released, and was performed at the first ever MTV Europe Music Awards held in Germany. By the end of 1994, they were an international commercial success.
The Bridge (1995–96)
Even though the band members were exhausted from two long years of international promotion, they could hardly believe how successful they had become. In April 1994, an obsessed German fan broke into the Berggren family home, brandishing a knife.
 After managing to restrain her, the band decided they needed
bodyguards. However, they were unable to take time to reflect before starting work on a second album because their record companies all over the world were demanding a swift follow-up. To speed up the process, instead of Jonas and Ulf writing the bulk of the album, each member was encouraged to submit their own tracks for consideration.
In the end, 17 tracks made the cut of the second album, titled
The Bridge. It marked a considerable change of direction in sound; out were the reggae and club sounds that made the group so popular in favor of a more experimental sound and several ballads. The lead single, "
Lucky Love", however, was a mainstream pop record, and upon its release in October 1995, it became the band's first No. 1 single in Sweden. This came as a pleasant surprise to the members, as they had found that their fellow Swedes had been their harshest critics. It charted at a more modest No. 13 in Germany, No. 20 in the United Kingdom and No. 30 in Australia.
Arista Records instead opted for the pulsating dance beat of "
Beautiful Life" for the first single in the US, where it peaked at No. 15. "Beautiful Life" was released as the second single from the album in most countries, reaching No. 15 in the UK and No. 11 in Australia, while "Lucky Love" was remixed in a new acoustic form along with a new video for the second US single from the album, peaking at No. 30. The Bridge was certified platinum in 14 countries, but the phenomenal success of the band's first album proved difficult to follow. "
Never Gonna Say I'm Sorry" was released as the third single from the album and achieved moderate success in Europe, but it failed to chart on the Hot 100 in the US. In February 1996, the band performed at the
Viña del Mar Festival de la Cancion in
Chile, topping the bill alongside
Flowers / Cruel Summer (1997–99)
After this, Ace of Base disappeared from the limelight for a while, emerging only in April 1997 for a performance at the World Music Awards and in July 1997 to perform at a concert to celebrate the 20th birthday of
Princess Victoria of Sweden. They were given as much time as they wanted to produce their third album, much of it being recorded in Jonas's own studio, "The Barn". When it was finally released in June 1998, the band declared it their best album yet. It was titled
Flowers because they believed that the songs, wildly different in style including
gospel influences, resembled a varied bouquet of flowers. Fans were surprised to see that singer Linn had relinquished lead vocal duties to sister Jenny, and on many promotional photos, Linn's face was blurred.
 They were reassured that Linn was happy with her new backing role in the group, and many reasons were given for her decision, including her having damaged her voice, fear of flying putting her off from traveling around the world and her dislike of fame.
Linn has relinquished the role of front vocalist and delegated her singing duties to sister Jenny. Linn has had recurrent problems with her voice since album II, The Bridge, and would not be able to withstand the rigors of touring. As it represents a significant change, the band has decided to concentrate all visual attention on Jenny for the time being.
—Ace of Base website, 1998
The radio-friendly single "
Life Is a Flower" was certified the most-played track on European radio for 1998 and sold more than 250,000 copies in the UK, peaking at No. 5; the colorful video of the same name was produced and directed by Andreas Neumann. British label
London Records had requested the band record the 1983 hit "
Cruel Summer", by
Bananarama and it was selected as the second European single. Deciding that "Life Is a Flower" was "too European in nature", Clive Davis pushed "Cruel Summer" as the lead-off single for the United States, and it brought Ace of Base back into the US Top Ten for the first time in four years, being certified gold. The album was also renamed
Cruel Summer and featured a different track list compared to the European release. For this version of the album, Davis persuaded a reluctant Linn to record the Billy Steinberg-penned ballad "
Everytime It Rains". "Life Is a Flower" was re-recorded as "
Whenever You're Near Me" and four other songs originally on Flowers were remixed and edited for the US release. "Whenever You're Near Me" was released as the second single from Cruel Summer, peaking at No. 76. "
Travel to Romantis" and "
Always Have, Always Will" were further singles in Europe while "Everytime It Rains" was issued as a single in the UK along with a repackaged edition of Flowers released only in the UK.
Singles of the 90s and Greatest Hits (1999–2000)
Singles of the 90s, a compilation of sixteen hit singles, was released in November 1999. Its first single, "
C'est La Vie (Always 21)", charted modestly in most places where it was released and went on to become a surprise No. 1 hit in Spain. Attempting to capitalize on the success of the previous single, "
Hallo Hallo" was released with special remixes just for the Spanish market. The album's marketing push closed with the limited radio-only single release of "
Love in December".
Greatest Hits was released for the American market in March 2000. "Hallo Hallo" was initially planned to be the first single from the compilation, but in the end, it was not included at all. "C'est La Vie (Always 21)" served as the only new recording on the American release. "
Everytime It Rains", previously included on the
Cruel Summer album, was released in a new remixed form as a radio single in the US, becoming the only form of promotion for Greatest Hits. With minimal promotion, the album and the single failed to chart, with the former selling fewer than 5,000 copies in its first week.
Da Capo (2002–03)
Linn of Ace of Base after a performance in 2002
Ace of Base released its fourth studio album,
Da Capo, on September 30, 2002, in Europe, and in Japan through
Toshiba EMI with a different cover and three bonus tracks. The album had originally been planned for release in mid-2000, but was repeatedly postponed due to record company complications. The album received only a soft release in the United Kingdom and was not released in America or Australia, though a release was planned for the United States in 2003.
 The album is named for the musical term da capo, which translates as "back to the beginning". It was intended to be a return to the band's earliest sound.
Although the album entered the album charts in many European countries, it was not as successful as previous releases. Only Jenny and Ulf went on a promotional tour of Sweden, Denmark, Norway, Finland, Germany, Poland and Austria. Jonas didn't attend promotional activities because "it was better to be two then" because it led to "less questions" about Linn's lack of participation.
 Linn attended only one performance in Germany, which was her last public appearance.
The first single release from the Da Capo album was "
Beautiful Morning", which peaked at No.14 in Sweden and No. 38 in Germany, where it was followed by "
The Juvenile"; this was used for a Christmas campaign by German TV channel
RTL. "The Juvenile" was previously written for the
GoldenEye James Bond movie in 1995. However, Arista, the band's American record label at the time, shelved the idea. In Scandinavia,
Edel-Mega released the album's opening track, "
Unspeakable", as the second single, but its poor chart performance ended the promotion of the album prematurely.
The band remained out of the spotlight throughout 2003 and 2004, although Jenny kept busy by performing solo live performances in several Christian shows with her by-then husband Jakob Petrén and released an album as a vocalist with the Swedish group Arose.
In 2005, a handful of songs featuring vocals by both Jenny and Linn were recorded.
 At the end of 2005, the band reunited, without Linn, for several live performances at the
Night of the Proms in Belgium, alongside other artists such as
Ace of Base reunited as a trio to perform their first full-length concert since 1996 in
Russia, on November 15, 2007. Further concerts followed throughout both 2008 and 2009; these were mainly in eastern Europe and
Singapore and the
Dominican Republic were visited briefly. The set list included various songs from their past albums and a new remake of their first single, "Wheel of Fortune". Linn was absent from the tour, and Jenny confirmed her departure from the band. "She hasn't been part of Ace of Base for several years", she said in
Se & Hør magazine.
 The remaining band members promised Linn that they would never ask her to rejoin the band again.
 While touring, the group performed live a new song called "Sparks from a Fire".
While on tour, the band recorded material for a new studio album to consist of seven new songs and seven remakes of old hits.
 However, this album did not see a release and a new greatest hits set,
Greatest Hits, was released on November 12, 2008, instead, reportedly due to record company obligations.
 The set was their second release with this title. The 3-disc set included one CD with hits, a second CD containing remixes, and a DVD containing music videos. Four re-recorded songs were released from the album in various forms: "Lucky Love 2009", "Don't Turn Around 2009", "The Sign (Freedom Bunch Mix)" and "Wheel of Fortune 2009", which was released worldwide on October 24, 2008, as a digital single.
 A fifth reworking, "Happy Nation 2009", was released separately as a remix kit. A remake of "All That She Wants" was recorded around this period and featured guest vocals by
Britney Spears that stemmed from her own 2007 cover of the song. This remake was never officially released, but leaked online in June 2016.
Following the release of the compilation, the band continued to record songs for a fifth studio album.
 A new record contract agreement was never reached, and Jenny announced that she was working on her own solo album, which later materialized as
 On November 13, 2009, Ulf, acting as a guest judge on
Idol 2009, announced that the band was negotiating with labels and was planning on releasing a new album in the beginning of the following year.
New members, The Golden Ratio, and Ace Thursdays (2010–12)
Ace of Base performing during a fan meeting in Toronto, Canada (2010).
In early 2009, Ulf and Jonas met Julia Williamson through a mutual music contact and began recording songs with her.
 During Ulf's period as a guest judge on Idol 2009, he and Jonas first met
Clara Hagman, who was later recruited as a member of the new Ace of Base line-up.
 Jenny stated that the new line-up would not be called Ace of Base, while Jonas remarked that they would "reform how [they] write the band name".
 This alternative line-up was later presented with a slightly changed name, "Ace.of.Base", but this was mainly a graphical adjustment used on the cover of their releases only.
Jenny said several times that she never left the band. On the contrary, she declared that all four original members were still band members and that, among the four of them, they owned the brand Ace of Base.
 Jonas noted in an interview that the record companies wanted a new, but not necessarily younger, vocalist alongside Jenny, to which she objected.
 He also said Jenny had never officially quit the band, but the record companies saw her as a leaving member. Ulf said in the same interview that "the record label demanded that we have two girls singing [...] Jenny wasn’t interested in doing that." Jenny said that neither Jonas nor Ulf had allowed her to participate in songwriting for the band's album.
 Clara noted that "I’m not here to take anyone's place [...] when I got this chance I understood that not everybody would accept me and Julia immediately".
The first release from the new line-up was "Mr. Replay", which appeared on a promotional DJ disc.
 The song received mixed reviews from critics, who felt it was too similar to their previous material.
 The first single from
The Golden Ratio, "
All For You", was serviced to European radio stations in the middle of July 2010, and it was released as a single on September 10, 2010. The Golden Ratio was released on September 24, 2010. The album entered and peaked on the German album charts at No. 20. "All For You" reached No. 38 in the official German singles chart. The title track from The Golden Ratio was planned as a future single in Sweden; however, it was released only promotionally.
 An acoustic version of the album was also in talks but never materialized.
 No further singles were released in support of the album.
Beginning in 2011, Jonas and Ulf began releasing previously unreleased material to fans via the band's official Facebook page and the website ReverbNation on a semi-regular basis in events they referred to as "Ace Thursdays".
 Writing sessions for new material took place throughout the same year.
 This material was to be released under a new name, however, following the band's tour of Canada and Brazil in 2011, new music was put on hold.
Departures and Hidden Gems (2012–present)
Ace Thursdays continued throughout 2012, but were discontinued in May 2013. In November 2012, Jenny was quoted as saying, "The rest of the band are doing other things. ... We’re just wishing each other luck at this stage. I have a dream that we’ll get back together, so I don’t want to bang anyone on the head".
The official Ace of Base website became defunct in 2013. In January 2014, Julia announced on her official Facebook page that she had left the band in 2012.
 She later confirmed that Clara was also no longer part of the band, saying on her Facebook page, "I never really left the group, one day I just didn't hear anything from them and it's the same with Clara. Like it went up in smoke; really strange".
On May 14, 2014, Jonas announced via Facebook that they were "working on something great" and that "Linn will be a part of it".
 On July 7, 2014, a remix
EP was released, featuring new remixes of "All That She Wants".
 On September 27, 2014, Jonas announced that members were filming a documentary chronicling the production of "All That She Wants" at
 The documentary was aired on the Swedish channel SVT as part of the Hitlåtens Historia series on March 18, 2015.
In December 2014 and January 2015, remastered versions of their first four studio albums, in both European and American editions, were released digitally. Each release featured a bonus demo or B-side track.
Hidden Gems, a compilation album consisting entirely of demos and b-sides, was released worldwide on March 6, 2015;
Would You Believe" was released as the first single from the album on February 27, 2015.
In October 2015, Ulf said of a future reunion, "With the right elements in the next few years, I don’t think it's impossible";
 however, in July 2016, Jenny remarked: "We won’t re-form. [...] We’re finished working together but we’re not finished being family together. We have a lot of fun plans in the future but no musical plans".
