Melancholic London R&B trio the XX swing by the Congress Theater on Saturday, a show I previewed as part of the Reader‘s Fall Arts issue. Like I said then, the new Coexist (Young Turks/XL) advances but doesn’t overhaul the XX’s skeletal, sensual sound.

On Monday the group released a video for Coexist standout “Chained,” which is today’s 12 O’Clock Track.
