Review: Having contributed to a recent Infrastructure compilation, Rrose moves to consolidate the relationship with Function's label with the release of a full EP. Arc has more in common with the producer's techno work for Sandwell District than last year's conceptual outing on Further, but this release still resounds to a deeply experimental approach. "Specimen 2" unites minimal, tonal sounds with an abstract rhythm. On "Specimen 3" a similar concept prevails, as Rob Hood-influenced, microscopic stabs cozy up to pitter-patter beats. Even the dance floor-friendly title track, with its bass-heavy pulse and doubled-up claps, has an atonal, abstract backdrop.
