World-class reissue label Light in the Attic moved into a large warehouse last year, which can double as a live venue. Now it presents the inaugural Summer Spectacular. The lineup features Black Angels singer Alex Maas playing solo, badass pianist Overton Berry tickling out soul-jazz gems, soul-pop farm-boy phenoms Donnie and Joe Emerson, and ex–Saturday Knights member DJ Suspence spinning hot cuts between performances. Also, Sub Pop, Beats and Bohos, and others will peddle records, and there’ll be much food for the hungry. (LITA warehouse, 913 NW 50th St,, 3 pm, free, all ages)
