The Traversable Wormhole remix series has already seen techno heavyweights Peter Van Hoesen, Marcel Dettmann, Chris Liebing and Surgeon offer stunning interpretations of the veteran US producer's basement techno. The latest two producers to step up are Terrene Fixmer and Tommy Four Seven. Fixmer maintains the momentum accrued from his recent album on Speedy J's Electric Deluxe imprint with an unrelenting peak time re-interpretation of "Exotic Matter", whilst CLR darling Tommy Four Seven is in typically hard form, turning "Spacetime Symmetries" into a heaving slab of concrete techno with a jack knifing beat. If you didn't know why Chris Liebing and Speedy J are all over T47, you do now.
