Some elaborately staged shows in the UK (using "The Sentinel" concept as the theme, and featuring props by the special effects team from "Doctor Who") failed to generate the needed interest, and by the time the band was ready to record their second album for EMI, Lowson decided to leave the band (and the music industry). In the wake of Lowson's departure the band recorded the "Knightmoves" EP with new singer Alan Reed, former vocalist and frontman with Abel Ganz (cf. Abel Gance). The centre-piece of the EP was the epic Sanctuary, and early editions of the EP also included a bonus 7" featuring two tracks recorded as demos. The band went on to record a second EMI album, "The Wedge".
