I am a big fan of The Black Keys. Recently DH and I went to see them in concert and they were fuckin’ AMAZING. If you get a chance, do go see them live; they sound even better live then they do on the albums.
They are still on tour  (http://www.theblackkeys.com/turnblue )  — go, buy the tickets right away; I’ll wait.

Little Black Submarines has been my favorite during this NSF proposal-writing season. It sends shivers down my spine (wait till about 1:10). And it KILLS in concert!

And of course, Lonely Boy:

They also did a mean rendition of A Girl Like You in concert
