There is a lot of music on this set, including the 30-minute "Oasis." This is a Live at the Village Vanguard recording by pianist Keith Jarrett and his European quartet (Jan Garbarek on soprano and tenor, bassist Palle Danielsson and drummer Jon Christensen). The pianist very much dominates the music but Garbarek's unique floating tone on his instruments and the subtle accompaniment by Danielsson and Christensen are also noteworthy.
