Germany’s Misc. outrocks Alter Ego’s “Rocker” with “Rocket Kontrol,” a massive electro-techno contraption sporting yo-yoing bass and power-drill acid sequences. On the remix EP, Pan/Tone, Matthias Schaffhâuser, and Frank Martiniq take the edge off the brutalism, reconfiguring Misc.’s low-end into tight-fisted funk; Schaffhâuser even adds disco strings. Areal’s Basteroid, though, ups the intensity with a grinding mix that throws off sparks.
