Getting the spit ‘n’ polish treatment from a cadre of mostly German techno producers, Paul Kalkbrenner’s music takes on a sleeker vibe than before. You don’t need to see Ellen Allien & Apparat’s name on their remix of “Queer Fellow”- a slowly percolating track filled with echoing scrapes of sound-to know it’s their handiwork. Alexander Kowalski gives Kalkbrenner’s popular single “Gebrünn Gebrünn” a booming, models-on-the-runway feel, while Modeselektor’s mix makes “Gia 2000” skip along at a rocksteady pace. Remixes can sometimes become personality clashes between artists, but these tracks exude a more collaborative vibe.
