Atomic Rooster is a British rock band formed by Vincent Crane and Carl Palmer, both previously with The Crazy World of Arthur Brown. Known for their dynamic shifts in style, the band is most associated with hard, progressive rock, particularly through their 1971 hits Tomorrow Night and Devil's Answer. After notable activity in the 1970s and early 1980s, Atomic Rooster reformed in 2016, bringing back members from their classic era with approval from Crane’s widow.
