This "festival of advanced music" is back with its annual salute to bass-music culture, with event's low-end rumblings coming courtesy of some of the multipronged genre's best artists. Sepalcure makes intense yet warm music that winds its way among dubstep, house, U.K. funky, drum ’n’ bass and the indescribable; Dutch bass master 2562 has great work out on Tectonic and Martyn's 3024 label. With Finland's Teeth, L.A.'s Nguzunguzu, Atlanta's Distal, the U.K.'s Throwing Snow and NYC's own Dave Q chiming in, IndieScreen's woofers are gonna get a workout.
