The band's current lineup features Weatherman (the only constant member), rhythm guitarist and lead vocalist Pepper Keenan (from 1989 to 2006, and since 2014), drummer John Green (since 2020, who first joined as a touring substitute for Mullin in 2018 until his death), and bassist Bobby Landgraf (who replaced Dean in 2024).
[5] In early 1986, Simon Bob Sinister (who had performed some backing vocals on Animosity the previous year) took over as COC's lead vocalist, with the EP Technocracy recorded "about six months after" his arrival.
[8] At the same time, the group also added second guitarist Pepper Keenan, who had originally auditioned for the role of lead vocalist but "wasn't really hitting the bill of what we were looking for singing-wise" according to Mullin.
[2] The new five-piece lineup released Blind in 1991 and toured extensively; however, during the early stages of production for a follow-up album in summer 1993, Agell was fired and Swisher chose to leave alongside him.
[5] COC's lineup remained constant throughout the rest of the decade, before it was announced at the end of 2000 that Mullin was to be replaced by Jimmy Bower due to a back injury.
