I can't think of anything offhand beyond the usual picks (Vampire Weekend, Fleet Foxes, CYHSY). So I'll borrow one from a guy I just ran into while walking back to my apartment:
Guy: You look like you're in a really good mood (I wasn't, actually). What are you listening to?
Me: The Minutemen.
Guy: I don't know them. Can I listen to a bit?
(I hand him the iPod earbuds. He listens to 20 seconds of "The Anchor," then hands them back.)
Guy: They're alright - not intense enough for me. I like stuff like Nine Inch Nails.
