BEACH HOUSE Woozy, off-kilter nuggets filled Beach House's self-titled EP, which earned guitarist Alex Scally and singer-keyboardist Victoria Legrand (French composer Michel's niece) a sweet spot on the indie radar last year. "Devotion," the Baltimore duo's full-length debut, is due in late February, and the new songs - a handful are streaming at myspace.com/beachhousemusic - are shapely, caffeinated variations on the group's delicately dark, eerily radiant sound. Beach House plays upstairs at the Middle East Upstairs March 31.
