In the mid-1990s, a band of Berlin outsiders, centered around the record store Hard Wax and studio Dubplates & Mastering, began reducing sonic pressure to pure grayscale essence. The labels Basic Channel, Chain Reaction, Main Street, Burial Mix and Rhythm & Sound tossed Detroit techno, Chicago house and roots dub beats in a compression chamber and squeezed out something entirely other. Two of the key people in the scene, René Löwe and Peter Kuschnereit, returned to Detroit to perform live (as Scion) and spin individual DJ sets. Tasty textures guaranteed. Support from Detroit's Patrick Russell and Drew Pompa of Blank Artists, your hosts for the evening. Friday, Nov. 13. Doors at 10 p.m. at Bohemian National Home, 3009 Tillman St., Detroit; $10.
