I rather like Gaslight Anthem. I caught them when they came through town for a gig at the Opera House. Their straight ahead rock sound with aggressive guitars and great stories had instant appeal to me.
Their new album, American Slang, is out June 15. You can check out a stream of the new album at NPR. Then mosey over to emusic or your fave retailer for your copy on the 15th.
I've only made it through the first couple of tracks myself so far, but it sounds uber-promising.
