Keys to Ascension is the video release of a concert by the progressive rock group Yes recorded live at the Fremont Theatre in San Luis Obispo, California in March 1996. It marked the first set of Yes concerts to feature keyboardist Rick Wakeman and guitarist Steve Howe since 1991, and the first to feature this exact five-piece lineup since 1979. The three concerts with the newly reunited lineup were followed by two double albums entitled Keys to Ascension (the other obviously called Keys to Ascension 2) featuring all new material alongside live tracks from the San Luis Obispo shows. This along with these companion albums were reissued in 2010 as the Keys to Ascension box set.
A world tour was abruptly cancelled when Rick Wakeman quit the band in mid-1996. He would not rejoin the band until 2002.
