I've got a review up at SFCV of Philip Glass's Cello Concerto No. 2, Naqoyqatsi, conducted by Dennis Russell Davies, played by Matt Haimovits, whom, oddly, I mention for the first rather far down in the review.
Long story short, the concerto is an interesting mix of same-old, same-old and new & novel. Let me put it this way: After the last time I listened to it, the chaser / palate cleanser was the incomparable Nixon in China.
If you like Glass, you'll like this piece. But if you're thinking of buying it and you don't have Songs & Poems for Solo Cello already, get the solo recording, with the wonderful Wendy Sutter, first. It's the better piece.
