Review: This mammoth sonic collection features the entire interpolation tapes series (0, 1, 2, 3), obsolete machines (alchemy vinyl masters + variant reworks) and the tape session remasters of obsolete machines [stage two] w/an unreleased mix by cv313. Includes both double CD albums and all 5 of the single CD releases including the vinyl remasters, nearly 20 years of recordings compiled into one collection. This is the sonic world of radius in its entirety, a deeper than the ocean floor sound experience unlike any other. As the sonic aficionado’s at Boomkat so eloquently stated, “Oceanic, intergalactic, timeless; total manna for dub house ambient fiends! Speaking of concealing brilliance in smoky space, here the principle is taken to far distant limits. Three tracks here are culled from Steve Hitchell’s cassette demos from the early 1990’s, led by the 16 minute “Ethersonic” which manages to be constantly shifting yet changeless, like the beating subterranean heart of a sleeping city; inhuman, incomprehensible, sublime in scale yet paradoxically comforting. Even by the standards of the Deepchord/Echospace axis, it’s a gorgeously enveloping embrace. The pleasure is prolonged by two equally long new remixes of the track by Hitchell and Rod Modell as cv313: they add watery sparkle and electric cracks, making new experiences that, while they can’t match the totalizing wonder of the original, stimulate other synapses. Of the two other old tracks, the distorting “Oscillation Range” in particular can teach supposedly lo-fi producers a thing or two about how much scope can be achieved with bare bones tech.
