We haven’t heard fromBTWCrocodiles since theirChristmas-themed 7-inchwith Dum Dum Girls. Turns out they spend the first half of 2010 prepping a followup to last year’sSummer Of Hate. Listen to first single “Sleep Forever,” and you’ll notice some changes — a cleaner sound, less snottiness in singer Brandon Welchez’s vocals. They owe some of that to producer James Ford, who is one-half of Simian Mobile Disco, and an accomplished Brit producer (Florence & the Machine, Arctic Monkeys, Klaxons, Last Shadow Puppets, etc). Welchez’s more open, optimistic voice fits the organ swells and swirls on “Sleep Forever,” a turn away from the darker tracks of their debut. It was the next logical step for the band, but it’s still surprisingly great.
