"CLK Recovery" is a peak-time banger for big rooms and big soundsystems, with a tense, sparse, three-minute intro punctuated with cavernously reverberant chord stabs before dropping into a powerful 4/4 techno workout. "Unglued" on the flip could almost be two or three tracks in one, pinned together by a wonked-up, jacking groove in the vein of A Made Up Sound.
