Captain Beyond was a rock group formed in Los Angeles in 1972 by ex-members of other prominent groups. Singer Rod Evans (b. January 19, 1947, Slough, Berkshire, England) had been with Deep Purple; drummer Bobby Caldwell had worked with Johnny Winter; and guitarist Larry Rheinhart (b. July 7, 1948, Florida) and Lee Dorman (b. September 15, 1945, St. Louis, MO, d. December 21, 2012, Laguna Niguel, CA) had been in Iron Butterfly. This lineup made their self-titled debut album for the Southern rock label Capricorn in 1972, after which Caldwell was replaced by Marty Rodriguez for their second album, Sufficiently Breathless (1973). Captain Beyond became inactive following the departure of Evans, but it was reorganized in 1976. Caldwell returned, and Willy Daffern was added as vocalist for Captain Beyond's third album, Dawn Explosion (1977), recorded for Warner Bros. Dawn Explosion was Captain Beyond's final effort. ~ William Ruhlmann
