The xx, London's purveyors of moody dream-pop--and recent Mercury Prize winners--slinked onto stage last night in Harlem in a cloak of fog, their faces barely visible under a kaleidoscope of sumptuous stage lighting. On this final leg of their American tour, Romy Madley-Croft and Oliver Sim shyly thanked the sold-out crowd as they glided through a set of achingly minimal love songs, slipping in a gauzy cover of the 1993 Robin S. dance hit "Show Me Love" as Jamie Smith tapped out backbeats on a finger pad drum set. A true concert experience for introverts, the rubber-band guitar plinks of "Crystalised" were as rowdy as the music ever got, but the band soaked the theater to its rococo rafters with their mix of lullabies gone exquisitely rogue. - jm
