The audio assemblages of New York-based sound manipulator Margaret Chardiet are made and conveyed with combative intent. As Pharmakon, she doesn’t go on pleasure cruises. Rather, Chardiet makes soundtracks for readings of Dante’s “Inferno.” There’s a stealthy sexual quality to her Dadaesque workouts on her latest release, “Bestial Burden.” From the bare-boned abrasion of “Body Betrays Itself” to the caustic pounding of “Autoimmune,” Chardiet uses her throat as a sensual weapon. It’s a sound tailor-made to weed people out. But if you like Thomas Pynchon, Hannah Höch and early Einstürzende Neubauten, it will be sweet music to your ears. She brings her tonal revulsions to Sediment Arts on Friday, Jan. 30. Richmond analog terrorists Mutwawa and noise-pushers Coteries set the divisive mood beforehand. Doors open at 8 p.m. Admission is $10-$15. sedimentarts.org.
