Crystal Castles. I've heard they are pretty shoddy live, but there's something about their recorded music that makes my brain think "If I had musical talent, I'd like to make something that sounds like that". To be honest I didn't have high hopes for their sophomore record as I find getting my hopes up only leads to eventual disappointment.
However that changed when I heard Doe Deer. This song packs so much unfettered lo-fi, energy and aggression into its 1:37 playtime that even after 20 listens it still leaves your heart racing and you gasping for air. I just hope the rest of the new album is as good.
