The sound of the band was a mix of rock and pop, but also covered more progressive rock territory in songs like "The Coming of Kohoutek", an instrumental from their Nexus album. When Ballard left the band after Encore, they took an even more progressive/fusion turn with their final Epic album Circus and then signed to a new record label (RCA) for the final 1975 album Counterpoints. By 2005, all albums, including compilations, have been re-released on CD, except Counterpoints.
