Some sonic communities grow even in isolation, in the lonely obsessive moments in the studio as time melts away. Deep inside the Detroit Underground nests a Berlin underground, chasing those resonant shared sounds. DU Berlin draws together some of that love felt through music in the German capital. It's not the wild city of reunification or *Berlin Calling* or tourist-style movies or the easyJet set. This is the side of the city that endlessly romances machines for the sheer joy of it, as The Allegorist titles her track, "until dawn." And with some big names and emerging, ranging from mainstays to veteran agitators, the Berlin DU crew have telegraphed each other through productions and mutual inspiration. The results vibrate and rumble with sympathetic frequencies, but never limited to grayscale or dithered palettes.
