Music in Fifths (). Philip Glass /pick only six or so/

Kyle Gann on Philip Glass:

In the ’70s I was blown away by Music in Fifths, Music with Changing Parts, Music in Twelve Parts, and Einstein on the Beach, in that order, and afterward I almost quit paying attention, because his music had already had all the effect it could have. 

I came at the music in the reverse direction, starting in the lat 80s. But at this point, I could live with just those four. Ok, not really. For middle period Glass, I've been particularly enjoying Koyaanisqasi, Akhnaten, and some of the piano music.
