In 2003, deep in Croydon's Online Studios, the roots of proper tech house - we said *proper* tech house - were spreading underground. It was here that Evasive label head Rob joined forces with Simon Copleston, aka. Iteration X, for a fresh collaboration under the new alias Rob & Si. The project followed the underground momentum built by Iteration X's earlier 'Timecheck / Liquid Logic' EP, and merged the individual styles of both into a unified, forward-pulsing, projectile sound. The result was 'Roll One Up / Zebras', the 2003 two-tracker reminiscent of the sultry out-breaths characterising much of the 2-step garage that would emerge in parallel at the time. 'Zebraz' is an extra-special dubbing; an aposematic m(s)onochrome moving through various echos, stabs and what sound like field recordings of startled wildlife.
