Nine Inch Nails
In 1994, Trent Reznor brought Lohner into Nine Inch Nails to play guitar, bass, and keyboards for the band live. Lohner stayed on with the band throughout the touring cycle to The Downward Spiral, both the recording and touring behind The Fragile, the live album/DVD And All That Could Have Been, and the recording of the Still EP. Lohner left Nine Inch Nails on good terms to focus on production work as Trent Reznor began working on the Nine Inch Nails album With Teeth. Lohner was featured on many NIN remixes during this time, and was featured on the Nine Inch Nails recordings of "Big Man With A Gun", "Somewhat Damaged", "Even Deeper", "The Great Below", various songs from Still as well as playing various instruments on every song on And All That Could Have Been. He was a guest performer with the NIN live band during their Wave Goodbye Tour in 2009.
He was featured on Marilyn Manson's breakthrough album Antichrist Superstar, as was most of Nine Inch Nails because of Trent Reznor's relationship with Manson, acting as his mentor in the world of music. Lohner can be heard playing the acoustic guitar on '"The Reflecting God" and lead guitar on "Angel With the Scabbed Wings."
Lohner worked together with Eminem and Marilyn Manson on the song "The Way I Am (Danny Lohner Remix)".
Lohner was involved with Puscifer's first album, 2007's "V" is for Vagina, and 2007's Don't Shoot the Messenger EP and 2009's "C" is for (Please Insert Sophomoric Genitalia Reference HERE) EP, helping with engineering, remixing, and filling in instrumentation as necessary.
After longtime bassist Jason Newsted left Metallica and the subsequent recording of the St. Anger album, Lohner was one of a select few musicians whom the band invited to audition for the empty bassist slot (Producer Bob Rock had recorded the bass parts for the album). Although he did not join the band, he can be seen briefly in the documentary of the making of the album and general turmoil in the band during that period, Some Kind of Monster.
A Perfect Circle
Lohner can frequently be found contributing to movie scores with fellow Nothing Records alumni Charlie Clouser and Clint Mansell. Additionally, he does remixes for various artists under the pseudonym Renholdër (an in-joke anagram of Re: D. Lohner). This began as a result of the song of the same title, which appeared on A Perfect Circle's debut album Mer de Noms. Contrary to popular belief, Lohner did not work on this song but was later told by guitarist Billy Howerdel that the song was about him. He has appeared in all of A Perfect Circle's albums to date in one form or another and has also appeared on stage with the band.
In early 2003, A Perfect Circle's official Web site announced that Renholder would be replacing Troy Van Leeuwen as the band's second guitarist. While Lohner did receive production credit on the band's second release, Thirteenth Step, he had other obligations by the time touring began, and ex-Smashing Pumpkins guitarist James Iha stepped in to fill the void. The most notable reason for Lohner's departure was his obligation to produce the soundtrack of the movie Underworld. This soundtrack was a collection mostly consisting of tracks written, produced, remixed, and performed by Lohner and his friends in the industry, including David Bowie, TRUSTcompany, Maynard James Keenan, Johnette Napolitano, and others. Lohner worked with Richard Patrick of Filter, Wes Borland of Limp Bizkit and Black Light Burns, and Josh Freese of A Perfect Circle and Nine Inch Nails, in a project called The Damning Well. Only one song, "Awakening", was released by the group on the soundtrack. Another track, "Coward", which originally featured Amy Lee of Evanescence on guest vocals, would eventually be reworked to be included on the debut album by Black Light Burns without Lee's vocals due to collaboration restrictions from her record label Wind-Up.
In November 2004, Lohner contributed heavily to eMOTIVe, the third full-length album by A Perfect Circle. This album was mostly a collection of cover songs, but it also included "Counting Bodies Like Sheep to the Rhythm of the War Drums," a continuation of "Pet" from the band's second album, Thirteenth Step. In addition, there was an original work, titled "Passive," which was the final version of a song originally composed for the Tapeworm Project. This track subsequently appeared on the soundtrack of the film Constantine, and Lohner appeared in the video for this track. A sister to eMOTIVe, 2004 also saw the release of aMOTION, a 2-disc collection that included a CD of the band's remixes and a DVD of music videos and live material. The remix album included Lohner's remixes of "3 Libras," "Judith," "Weak and Powerless," and "The Outsider." Although these remixes had previously been available on various soundtracks and CD singles, 3 Libras was reworked slightly from its original release, and "Judith" now featured censored lyrics. On both eMOTIVe and aMOTION, Lohner was credited as a band member.
30 Seconds to Mars
Lohner was involved with Thirty Seconds to Mars in programming on their track "Fallen" from their self-titled album.
Black Light Burns
In 2005 and 2006, Lohner was involved further with Wes Borland in a project called Black Light Burns, taking on the role of producer as well as playing guitar, bass, synth, programming, and more. The project was somewhat of a successor of the Damning Well, as it involved most of its members, as well as certain portions of still unreleased material from the Damning Well. Other members included Josh Eustis of Telefon Tel Aviv and Josh Freese. The album was released on June 5, 2007, to be followed by a tour that Lohner was not able to participate in because of his current activities, despite Borland's effort to get Lohner to join the touring lineup.
He also worked with the popular Japanese rock artist HYDE in 2005–06, recording bass tracks along with Craig Adams on Hyde's album Faith.
Lohner co-produced the album Keep Telling Myself It's Alright with his old bandmate Billy Howerdel for Howerdel's solo project ASHES dIVIDE.
Angels & Airwaves
He was also involved with former Blink-182 member Tom Delonge and his new band Angels & Airwaves in producing and programming on its track "Distraction" from its We Don't Need to Whisper album.
Fear and the Nervous System
In March 2008, it was announced that he was going to produce the debut album of Korn guitarist James "Munky" Shaffer's solo project Fear and the Nervous System.
In December 2008, Genghis Tron released Board Up The House Remixes Volume 3 (of a five-part vinyl released remix series) via Relapse Records. Lohner contributed his remix of the band's title-track song from its 2008 album, Board Up the House.
Lohner produced rap rock band Hollywood Undead's CD/DVD, Desperate Measures, release on November 10, 2009. He also did a remix (under the alias 'Castle Renholdër') for the band's song from their debut album, "Everywhere I Go", and produced the songs "Dove & Grenade" and "How We Roll". Lohner also provided production on the band's 2008 debut album Swan Songs, and their 2012 single "We Are".
Lohner produced Crisis in Utopia, the debut album of the Californian heavy metal band Holy Grail. The album was released on October 26, 2010(in the USA).
Lohner produced Smite and Ignite for the fictional League of Legends band Pentakill, released June 3, 2014.
