CKY (short for "Camp Kill Yourself") is a 4-piece rock band consisting of Deron Miller (vocals, guitar, bass), Chad I Ginsburg (guitar, vocals, bass), Jess Margera (drums), and Matty Janaitis (bass). Deron and Chad both played bass on all 4 of their albums, but Matty will take over when they record their next album, and he has now taken over for their live shows. They share their name with a series of skate videos produced by Bam Margera, who is the brother of the drummer.
