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, there are currently two lineups using the name – one with Ginsburg and Margera, and another with Miller. Closely linked to the CKY Crew, which features Margera's brother Bam, the band found initial recognition through its musical contributions to the CKY video series, and also later to the related TV series Jackass.
Originally known by the full name Camp Kill Yourself, and later credited briefly as simply Camp, the band released its debut album Volume 1 in 1999, 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, with latest studio album Carver City 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. Songwriting is typically led by Miller, with production, engineering and mixing handled by Ginsburg. In recent years, internal tensions between band members have halted progress on new material and touring, and the future of CKY remains unclear.
