Most famous for including bassist Roger Glover and singer Ian Gillan before they joined Deep Purple, Episode Six managed to release no less than nine British singles between 1966 and 1969 without coming close to a hit record or establishing a solid identity. Also prominently featuring organist/singer Sheila Carter-Dimmock, the group's 1966-1967 singles were rather light pop/rock harmony numbers, with an occasional ballad and a bit of a soul influence. Light years removed from Deep Purple, Episode Six was nothing if not eclectic in their choice of material, trying their hands at numbers by the Hollies, the Beatles, the Tokens, and Charles Aznavour, as well as a British hot-rod tune (written by Glover). While their repertoire lacked focus, their singles were actually pleasant and their fine cover of Tim Rose's "Morning Dew" would have been a deserving hit.
In 1967, they began to fuse pop and psychedelia with reasonably impressive results, especially the single "I Can See Through You" (written by Glover), one of the finest British psychedelic obscurities. Their final two singles showed the band going in a much more progressive direction and anticipating some of the most indulgent art rock of the '70s with "Mozart Versus the Rest," which assaulted one of the composer's most famous riffs with manic electric guitars. Episode Six folded in 1969, after Gillan and Glover had joined Deep Purple.
