The Who's Roger Daltrey has opened up about the current state of rock music and says there's just not enough anger in music anymore.

Speaking with the U.K.'s London Evening Standard, Daltrey said that art is no longer at the center of the music business and the quality of work is lagging as a result.

"There's not enough anger out there in the music," he said.

"We will always do shows for charity, when we can, because it's of enormous value to people and Pete Townshend and I love to play.

But we won't do long, schlepping tours. It's killing us," he explained.
