I'm on a Gaslight Anthem binge right now, and I remember everything I loved about them. They're basically Bruce Springsteen, if he was the frontman of a punk rock band. They have the same raw but soulful New Jersey local flavored sound that Springsteen does, but it's very modern and alternative influenced too... but you don't need to be a Bruce fan to like Gaslight.
Brian Fallon is a great vocalist, and a great songwriter.
I'd recommend their debut album, "Sink or Swim", for anyone getting into them, although my favorite song of theirs is still probably "45" from their most recent album, "Handwritten".
