Captain Beyond was a US rock band formed in Los Angeles, California in 1972. Its members were singer Rod Evans (from England), guitarist Larry Rheinhardt ("Rhino" ), bassist Lee Dorman, and drummer Bobby Caldwell. Evans was a former singer in Deep Purple, and Rheinhardt and Dorman had their past in Iron Butterfly. Caldwell had come to prominence playing with Johnny Winter. He was replaced by drummer Martin Rodriguez on the group's second album. After that album Evans decided to leave the band. Captain Beyond re-formed again in 1976, with singer Willy Daffern, and Caldwell back on the drums. Captain Beyond played hard rock influenced by progressive rock. Although the band achieved very little commercial success, the group nevertheless has become a cult band and its influence is felt today as legions of newcomers are discovering their work.
