Drone Activity in Progress

Red Bull Music Academy. Long before the term drone took on unfortunate death-from-above connotations, it mostly referred to a less-is-more school of musical thought in which primordial sounds could be made to yield metaphysical ends. Tonight's RBMA showcase gathers some of the scene's biggest players, including Sunn O))) guitar magus Stephen O'Malley and his coterie (Oren Ambarchi, Peter Rehberg); ex–Sonic Youth Kim Gordon; Dominick Fernow, the altered ego behind Prurient and Vatican Shadow; and plenty more. The rock-bottom price tag is just one more incentive.
