Flotsam and Jetsam is an American thrash metal band that was formed in Phoenix, Arizona, in 1981. Before settling on its current name in 1984, the band had existed under three different names, Paradox, Dredlox and Dogz. Their current lineup includes vocalist Eric "A.K" Knutson, guitarists Michael Gilbert and Steve Conley, bassist Bill Bodily, and drummer Ken Mary. Flotsam and Jetsam went through several lineup changes over the years, leaving Knutson as the only constant member. They are also notable for featuring a then-unknown Jason Newsted, who was Flotsam and Jetsam's bassist from 1981 to 1986, when he left the band shortly after the release of their debut album to join Metallica. Flotsam and Jetsam has released fourteen studio albums in their career, with the latest being 2021's Blood in the Water.
