Steve Zing drummed for Implosion, Mourning Noise, and The Undead before joining Samhain. He graduated from Lodi High School with Eerie Von and Doyle Wolfgang von Frankenstein. Steve left Samhain shortly after the Unholy Passion EP was released. He was replaced by London May and returned briefly to The Undead.
In 1999, Steve returned to Samhain for the reunion tour, playing the first half of the show on drums, and the second on bass. He later recorded with Son of Sam, which included AFI vocalist Davey Havok, then-Danzig guitarist Todd Youth and former Samhain and Tiger Army drummer London May. The album featured guest appearances by Glenn Danzig and then-Danzig drummer Joey Castillo.
Steve now fronts his own horrorpunk/heavy metal hybrid band, Marra's Drug. The band's first album Down Below was released on Long Live Crime Records, an indie label in Los Angeles.
He also tours with Danzig playing bass, and the band occasionally plays Samhain songs live.
