As a member of the xx, producer/multi-instrumentalist Jamie Smith has found his own private corner of modern music-making, actively blending of-the-moment electro beats and samples with bits of steel drum, percussion and keyboard. The Mercury Prize-winning indie rock band returns this week to one of the big Coachella stages, performing their whispery songs on love won and lost from last year's Coexist. Smith remains deeply committed to the xx trio, but he's kept busy between tours as a world-traveling producer, remixer and in-demand club DJ. (See his surprising 2010 collaboration with the late Gil Scott-Heron, We're New Here, and his remixes of Radiohead's "Bloom.") Aside from the xx’s Coachella performances, Smith will appear solo in front of the EDM contingent for a DJ set certain to contain echoes from his obsessions with the electronic and deeply emotional.
