His central role in the East Coast metal scene would later be an essential factor in launching the career of Metallica. Zazula offered the band their first opportunity to play in the New York area and organized their first tours with Raven, one of the leading metal bands from the UK at that time. After hearing the demo tape No Life 'Til Leather, he founded the label Megaforce Records to release their work. Zazula released Metallica's debut album Kill 'Em All and set up an East Coast tour with private funding.
After the success of Kill 'Em All, Zazula signed and worked with other artists including: Warren Haynes, Testament, Tad, Overkill, Frehley's Comet, Kings X, Ministry, and Anthrax.
