Repeat is the duo of Toshi Nakamura and Jason Kahn, the former on his patented no-input mixing board, the latter on percussion and electronics. The music hovers midway between the extreme abstraction Nakamura has created with Sachiko M or Keith Rowe (do and Weather Sky respectively, both on Erstwhile) and the more tonic, loop-driven work on his own solo discs. There tends to be a pulse, or several, at work at any given moment, often of differing periods and textures. The textures themselves usually come in varied flavors even as they're laid out simultaneously; a dry hiss will wind through a creamy, deep drone which, in turn, flows alongside ringing, bell-like tones forming an aural lamina of juicy contrasts. Sometimes, as on the third track (all cuts are untitled), there's the slightest whiff of science experiment as the struck bells sidle next to the pure sine tones and create absorbing interference patterns, all arrayed over low, throbbing drums. Most of the tracks meander delightfully in this general area. Sometimes gently swirling little whirlpools of static leave whispering eddies of tonal pulses in their wake that gradually coalesce into sharp crusts of sonic debris. Elsewhere similar patterns spin out into entirely different, dissimilarly patterned territories. When the final cut deluges the ears with a cascade of bells, pings, bongs and clicks, sonic bliss is achieved. Listeners who enjoyed the wonderful Radian disc, "rec.extern" and want to hear that sort of aural concept pushed several degrees further could do worse than checking out this fascinating recording.
