I just got Philip Glass's
Solo Piano album. A bunch of reviewers on
Amazon hurl brickbats at Glass's piano-playing--complaining that what would otherwise be excellent music is spoiled by his less than technically perfect playing.
After a few listens in the headphones, I agree-- Glass does seem to stumble in a few places. Where the patterns speed up, you can hear him start to go a bit uneven.
That said, I don't think it detracts unduly from the recording. The five pieces in the "Metamorphosis" cycle are hauntingly simple. Repetitive, yes, but not droning or overwhelming in the way that, say Einstein at the Beach can be. For "out-there" music, it's pretty accessible and (to me, anyway) eminently listenable.
Here's the most famous piece, "Metamorphosis Two"

I really need to go watch The Hours now, because I've heard snips of Glass's score.
