Spread across two discs, these studio interpretations of a live performance from 2017 deftly distil Bill Thompson's artful approach to guitar, one deeply indebted to Keith Rowe's abstract table-top deconstructions. Throughout Mouthful Of Silence the listener is reminded of Rowe's zen-like ideas championed during his tenure with AMM, in particular his need to assimilate his own sound within the ambience of a performance space and beyond. But these finely-tuned panoramas, summoned by the sustain of Thompson's specially modified Moog instrument, owe as much to the minimalist drones of Alvin Lucier and Eliane Radigue as they do to any long-form improvisation. Oscillating beneath the surface of their mother-tone percolate a multitude of rogue timbres and phantasmal clusters, cherishing the menace of whitenoise bleed and bobbing like digital buoys in the wild flux of Heraclitus' river.
