Given the talent involved, you'd expect this collaboration between Detroit veteran Keith 'K-Dub' Worthy, Steven Tang and Jamal 'Hieroglyphic Being' Moss to be rather special. Predictably, it's excellent. The A-side boasts two versions of "Rarefied Air" from Worthy, who delivers nothing short of emotion-rich Detroit techno brilliance, complete with bouncy synth bass, swirling deep space melodies and restless percussion. The Dub, in particular, is superb. On the flip, Moss makes the track raw and uncompromising, layering twisted acid lines atop a thumping, tribal techno groove. Tang closes proceedings with a version that sits somewhere between the two schools, placing a long spoken word vocal sample atop mind-bending electronics, spacey chords and hissing percussion.
