Yeah, Brubeck is a classic, a standard, but Phillip Glass, that's not your everyday item at all. I love the soundtrack to the trilogy Koyaanisqatsi Powaqqatsi and Naqoyqatsi as much as I love the movies themselves, but I think he did great work for The Illusionist also. But I adore The Photographer which was based on the life of Edweard Muybridge.
But I pretty much adore anyone who studied with Nadia Boulanger - in a world of pop crap music, she makes the gold.
