Zoetrope was an American heavy metal band from Chicago, Illinois.
 Although their sound was akin to thrash metal, the group described themselves as "Street Metal".
 The group was formed in 1976 by teenage friends Barry Stern (drums/vocals), Kevin Michael Rasofsky, aka Kevin Michael, (guitar), and Calvin "Willis" Humphrey (bass), soon to be joined by second guitarist Ken Black.
 Initially playing covers, the band soon ventured into writing their own material and released a single in 1980.
 Although undeniably a metal band, Zoetrope was also active in Chicago's hardcore punk scene, sharing bills with locals hardcore bands and hanging out at O'Banions, a Chicago punk bar (Ken Black and Barry Stern also produced the self-titled LP by Chicago-based hardcore band Life Sentence in 1986).
 Following the release of a couple of demo tapes, the group was signed to Combat Records and issued their first LP, "Amnesty", in 1985.
 In 1987, the band traveled to Los Angeles to record their follow up, "A Life of Crime", with producer Randy Burns (Megadeth, Nuclear Assault).
 During the recording sessions, Ken Black left the band and returned to Chicago to sort out substance abuse issues.
 He was replaced by Louis Svitek.
 Although Svitek appears on the album's cover, Kevin Michael later confirmed that Ken Black had finished his guitar parts before leaving Los Angeles.
 During the tour supporting "A Life of Crime", Svitek was recruited for M.O.D. by Billy Milano.
 After the tour, Barry Stern jumped ship to fellow Chicagoans Trouble.
 Kevin Michael eventually returned with a new line up for 1993's "Mind Over Splatter" but the band folded for good soon after.
