As far as big stadium concerts, I'd say DMB, U2, Radiohead.
However, on a smaller scale, I just saw the most amazing indie band up in Portland. Their name is Amelia
, and they're in the same genre as My Morning Jacket, Elliott Smith, etc. I am usually a little skeptical about small shows (been to a lot) but I'm really in love with this band. If they're playing near you.....go!
