At Berlin’s Night + Day Festival over the weekend, the xx invited Jessie Ware, their peer in warm, poised, inward-looking London club music, to the stage for something very cool. Over the track from Jamie xx’s “Sunset” edit, they fused together two circa-2000 rave classics: Modjo’s “Lady (Hear Me Tonight)” and Stardust’s “Music Sounds Better With You.” The xx handled the “Lady” hook, while Ware sang the everliving hell out of “Music Sounds Better With You,” and the whole thing just sounded awesome. The Berlin crowd, bless them, knew both hooks well enough to sing along. Watch a prettily filmed, pristinely recorded video of the performance below.

At this point, I’m not sure there’s a single contemporary band with better taste in pop music than the xx, real talk.
