The fifth lesson in Physical Education is another hardcore sweatathon across four tracks of lithe techno, so you best put on your best kit and get ready to get down and dirty. 'Bass Equations' blends the old with the new, the jacking beats with the sci-fi synths. 'Dynamic Control' then ups the ante and heads down a soulful, Detroit styled machine techno groove with 'Hydro Cycles' cutting loose on an interplanetary exploration with cosmic winds and twinkling astral bodies floating by. Lastly, 'Reflexed' has driven by a well defined bassline as bright synths sing up top.
