Though Plain White T's is kind of an alternative sound, this week I've also listened to French/Irish early-renaisance style music, latin jazz, latin pop, a modern string trio sound thing (Nickel Creek, hard to explain), a capella music (Rockapella), and classical.
The list might go on, that's just what popped into my head first. Diverse enough for you?
I've been listening to Jack's Mannequin and, since I went to their show, Copeland. I've also been hooked on Rent (saw it 3rd row in September) and The Producers.
