The xx + Sampha

The xx manages to communicate volumes in its elegant, subdued and understatedly sensual songs. The last time the deservedly fussed-over London trio touched down in the city, the transmissions were fittingly intimate: a 25-show residency with 40 people at each gig. In support of the newly released third studio album, I See You, though, the band notches the volume back up as it returns to the stadium stage.
