Keys to Ascension 2 is the fifth live and sixteenth studio album by the English progressive rock band Yes. It was released as a double album in November 1997 by Essential Records as the successor to the previous live/studio album Keys to Ascension. After guitarist Steve Howe and keyboardist Rick Wakeman returned to the band in 1995, the group relocated to San Luis Obispo, California and started to write new material. The reunion of this particular line-up was promoted with three concerts at the city's Fremont Theater in March 1996, the five's first live performance together since 1979. Keys to Ascension 2 features the remaining half of the live set from the 1996 shows and five new studio tracks including two which marked a return to the group writing long-form pieces.
