Knee Play 1 (live) - Philip Glass, “Einstein on the Beach“

Recorded live at The Green Space in NYC (prior to recent revival of Einstein on the Beach at Brooklyn Academy of Music): PHILIP GLASS: AN HOUR WITH EINSTEIN Saturday, September 8, 2012 3:00 PM Note: I found the hour-long recording on the greenspace site buggy and difficult to stream, and thought people might enjoy having just the music tracks (without the commentary).
