Avant-garde composer Philip Glass turned 75 in January, and while you probably forgot to get him something, some high-profile collaborators are looking to pay tribute on a new remix album. The compilation comes out June 26 and will be overseen by Glass, producer Hector Castillo, and Beck, who helped recruit a roster of artists that includes Amon Tobin, Cornelius, Memory Tapes, Tyondai Braxton, Johann Johannsson, Nosaj Thing, and Sliver Alert, among others. Along with the remix project and several live events, Glass is marking his birthday by publishing his memoirs later this year.
