Product DescriptionOrange Mountain Music presents the Philip Glass Retrospective, a 2CD set of repertoire from the PGE's 40-year career. From a live-recording made in Monterrey Mexico in 2006, the set features music from Music in 12 Parts, In the Upper Room, Koyaanisqatsi, Einstein on the Beach, The Photographer, Glassworks and much more in its 100 plus minutes of music. The Philip Glass Ensemble was formed in the late 1960s as a vehicle for Philip Glass' new music. The image of the group, an ensemble of keyboards and woodwinds, became the iconic visual image for Philip Glass the performer. The ensemble continues to tour the world including complete performances of the seminal Music in 12 Parts and as the 'orchestra' for the most groundbreaking opera of the 20th century, Einstein on the Beach.
