Keys to Ascension is the fourth live and fifteenth studio album by English progressive rock band Yes, released as a double album in October 1996 on Essential Records. In 1995, guitarist Trevor Rabin and keyboardist Tony Kaye left the group which marked the return of former members Steve Howe and Rick Wakeman, thus reuniting them with vocalist Jon Anderson, bassist Chris Squire, and drummer Alan White, a line-up that had last performed in 1979. The group relocated to San Luis Obispo, California to make a new album and to promote their reunion with three shows at the Fremont Theater, in March 1996. Keys to Ascension features half of the live set from the 1996 shows and two new studio tracks which marked a return to Yes writing longform pieces.
