Awolnation is no doubt one of the leading rock performers of the era.  His performace on Jay Lenno featured his hit on the Iron Man 3 soundtrack, titled 'Some Kind of Joke'.  The catchy back up vocals makes this a song to sing along, not to mention the choice of backup singers added richness and depth to the song.  It seems like when Awolnation releases one hit another is soon to follow, needless to say Aaron Bruno is on a roll and I don't think he will be going anywhere in the near future.
