Atomic Rooster were an English progressive rock band, composed of former members of the The Crazy World of Arthur Brown. Throughout their history, keyboardist Vincent Crane was the only constant member, and wrote the majority of their material. Their history is defined by two periods, in the early 1970s and the early 1980s. Their genre in music is difficult to define, since they went through radical changes in very short times during the life of the band. However, their best-known era represented a more hard rock/progressive rock sound, exemplified by their only hit singles, "Tomorrow Night" (UK #11) and "The Devil's Answer" (UK #4), both in 1971.In summer 1969, The Crazy World of Arthur Brown had to cease touring in the middle of their second U.S. tour because of keyboardist Vincent Crane's mental illness. When he recovered, he and drummer Carl Palmer took the step to leave Arthur Brown and return to England, the return date being Friday 13 June 1969, which was the year of the Rooster in the Chinese calendar, and arranged a meeting with Brian Jones to discuss a collaboration. After his death, they adopted the name Atomic Rooster (with influence from the US band Rhinoceros), and soon recruited Nick Graham on bass and vocals. They followed with what had emerged as The Crazy World of Arthur Brown formula of vocals, organ, bass, and drums.They soon undertook live dates around London; at their first headlining gig the opening act was Deep Purple. They eventually struck a deal with B & C Records and began recording their debut album in December 1969. Their first LP, Atomic Roooster was released in February 1970, along with a single, "Friday the 13th". By March, Crane felt it was best that they add a guitarist, and recruited John Du Cann from acid/progressive rock band Andromeda. However, just as Du Cann joined, Graham left. Du Cann (who played guitar and sang for Andromeda) took over vocal duties, whilst Crane overdubbed the bass lines on his Hammond Organ with a combination of left hand and foot pedals. Atomic Rooster resumed gigging until the end of June, when Carl Palmer announced his departure to Emerson, Lake & Palmer. Ric Parnell filled the drum spot until August, when the young Paul Hammond was recruited from Farm to the drum spot. They then recorded their second album, Death Walks Behind You, released in September 1970. Originally it was not commercially successful, as with the first album, but by February 1971, the single, "Tomorrow Night" reached #11 in the UK Singles Chart, with the album reaching #12 in the UK Albums Chart.[1] Atomic Rooster made an appearance on the Top of the Pops, and toured to support their music.- ALBUM INFORMATION:Tracks:01.
