This side project from Sad» producer/sideman Stuart Matthewman channels all the pent-up artistic creativity accumulated during the eight long years between Sad» albums into 14 crucial-if not essential-tracks that effortlessly traverse the borders between R&B, electronic music, dancehall and dub. The “By Your Side” remix is more strident than anything on the narcolepsy-inducing Lovers Rock, while Manjit’s Arab-esque vocals on “Take Me Away” deliver discotheque exotica without becoming corny. Both tracks are trumped by a majestic re-fix of Gregory Isaacs’s classic “Night Nurse”-a cover that somehow makes the Cool Ruler sound even cooler.
