In typical Matt & Kim DIY fashion, the duo wrote and recorded their fourth album, Lightning, in their Brooklyn apartment. Talk about resourceful! (Sorry, neighbors.) Still, their snotty, electro-pop party jams are as hyper and bubblegum-sticky as ever. Matt's a big fan of the oh oh oh's, and he tends to repeat the title of the song a lot, which means shout-alongs galore. Single "Let's Go" is a bit Foster the People innocuous, but it gets more fun when Kim tears up the drums ("Much Too Late") and when the blips and bass (dubstep?) start to rumble on tracks like "Now" and "I Said."
