Lost in the Trees build powerful chamber pop out of deep pain. Singer Ari Picker dumps out demons every night, purging himself with a wavering croon that bursts into a powerful cry. He sings of broken feelings left behind by a very broken family, and the tight six-piece behind him never fails to lend support. Bold strings tangle with often searing guitars, twisting into thorny brambles. Picker puts his confessions to rest as rapturous melody and harmony take bloom, capturing beauty from all the grief. The Toddlers and Towers also play. $12/ 9 p.m. —Jordan Lawrence
