The British duo F*** Buttons are probably suffering—to some degree—from the downside to having a name that requires asterisks for certain media outlets. Slow Focus, the duo’s third full-length release, shows again that the Buttons—what with all the permutations the name is subjected to—are incredibly good at what they do. Rhythmic machinations push and pull squealing, pinging, whooshing, humming synths and brittle, staccato percussion into a myriad of shapes and forms, and their instrumental prowess shows a keen awareness of how critical it is to put something fresh into each track. Two guys (Andrew Hung and Benjamin Power, who met in art school in England) use a bunch of electronic gear—and other odds and ends—to make some utterly entrancing music, all without lyrics or anything like a “hook.” You can headbang to “Brainfreeze,” zone to “Stalker,” and get robot funky on “Sentients.” You won’t sing along or hum a melody in the shower, but the Buttons have made sure you'll remember.
