Through the pioneering work of AMM, percussionist Eddie Prévost has spent half a century patiently exploring improvised music frequently defined by space, hush and texture. In its current incarnation as the duo of Prévost and pianist John Tilbury, AMM's sound often hints at an aesthetic informed by the nakedly vulnerable note clusters of minimalist composer, Morton Feldman, with the piano chords' ineluctable decay almost more important than their initial statement. In this environment, Prévost has plenty of room to investigate the harmonics and rumbling drones that can be teased out of a bowed tam-tam. The trio with Wright and Lexer is equally uncluttered. Saxophonist Wright offers thin harmonics, sour notes and weedy braying, while Lexer nudges metallic rattling and muted harpsichord-like tones from his piano+ (a self-designed piano preparation that uses microphones and bespoke software to manipulate the strings' acoustic properties). Who else but Prévost would have the courage to sit back and simply let a snare buzz and fizz with the movement of the sound in the room?
