Check out the Kronos Quartet and Clint Mansell for some darker stuff with a lot of strings. Soundtrack to Requiem for a Dream was made by them. Otherwise I don't mind some classic classical like Vivaldi, Beethoven, and the other greats. I find I can't concentrate long enough on listening though, which is why it doesn't appeal too much to me although it sounds good.
