Just when the unending tide of DJ-mixed albums was really starting to get you down, a Berlin DJ/producer and a Liquid Liquid legend team up to bring you this masterpiece. Aiming to emulate the eclectic, rhythmically avant-garde mixes of late-‘70s cosmic disco, they match the genre’s inventiveness with a perfectly realized mix, one that even features a dubbed-up intro by Sal P. With 25 tracks-mostly obscure mind-blowing ones-Kaos and Sal P have upped the ante, big time.
