CKY is an American heavy metal band from West Chester, Pennsylvania. Formed in 1998 by vocalist and guitarist Deron Miller, guitarist Chad I Ginsburg and drummer Jess Margera, the group currently features Ginsburg, Margera and bassist Matt Deis, who have also performed with frontman Daniel Davies twice since Miller's departure in 2011. Closely linked to the CKY Crew, featuring Margera's brother Bam, the band found initial recognition through its musical contributions to the CKY video series and the TV series Jackass.
Originally known by the full name Camp Kill Yourself, and later briefly credited as simply Camp, the band released its debut studio album Volume 1 in 1999, which was largely made up of material recorded for the CKY films. The group later signed with The Island Def Jam Music Group and released Infiltrate•Destroy•Rebuild in 2002, which gave the band its first experience of US chart success. An Answer Can Be Found followed in 2005, before latest studio album Carver City was released by Roadrunner Records in 2009.
CKY has been categorised as a band of multiple musical genres, including alternative metal, post-grunge and skate punk. The band's songwriting in the past was typically led by Miller, with production, engineering and mixing handled by Ginsburg. In recent years, internal tensions between band members halted progress on new material and touring; Ginsburg, Margera and Deis have since retained the CKY name, while Miller has reformed Foreign Objects and started a new version of the band as MechaCKY.
