No living musician can challenge the joint eclecticism and influence of Philip Glass‘ five-decades-and-counting career. From his countless solo piano releases, string quartets, operas and symphonies to his towering soundtrack work and collaborations with the likes of Bowie, Patti Smith, Aphex Twin, Brian Eno, Allen Ginsberg, Ravi Shankar and David Byrne, the Baltimore master hasn’t as much left his stamp on contemporary classical music than irrevocably altered the course of it. To celebrate his 80th birthday today, we’ve compiled a 30 track, decade and genre-spanning Spotify playlist featuring some of his greatest moments.
