An online acquaintance of mine turned me on to a new band called The Fratellis. Their debut LP "Costello Music" won't come out in the US till March, but they're already quite big in the UK. Despair not, however. You can download their US EP -- "Flathead" -- though iTunes. It's great stuff... power pop but with an urgency that just screams "LISTEN!"
You can sample their stuff here or visit the iTunes store.
