Electronic duo Tom Rowlands and Ed Simons have trouble expanding their signature block-rocking sound on their fifth album. Pushing the Button. Once groundbreaking, the Chemical Brothers’ mix of big-beat thumps and psychedelic swirls sounds a bit dated nearly eight years after their Dig Your Own Hole heyday. The pair still have a knack for dance-pop songcraft, as shown on the roller-disco-ready ”The Boxer,” but if these Brits wish to stay relevant, they should seek out some new buttons to push.
