Their hardcore punk-oriented 20-track debut "Eye for an Eye"—the only album featuring Eycke—was initially released in 1984 and later re-released by Caroline Records in 1989. Soon after, Eycke left the band and COC continued as a three-piece with Dean and Mullin sharing vocal duties on 1985's follow-up "Animosity". In 1987, COC recruited Simon Bob Sinister after the breakup of their fellow Carolina band and Death Records labelmates Ugly Americans. The band's 1987 release, "Technocracy," featured the hectic crossover thrash musicianship of COC with a cleaner vocal style than they had in the past.
