U2 is hoping to release their next album in April. They continue to work on it in New York with producer Danger Mouse, a collaboration that some find to be a bit strange.

The Edge says, "I think we're still figuring that out ourselves. Those who have heard some of the tracks say it has traces of The Clash, Sex Pistols and Kraftwerk, which Bono says was "stuff we were really listening to when we were younger."

This will be their first album since 2009's No Line on the Horizon.
