On the two albums he's made with his Electro-Acoustic Ensemble, Toward the Margins and the new Drawn Inward (both just released, strangely, on ECM), Parker, Guy, Lytton, and violinist Phil Wachsmann improvise cumulous swirls of sound that get processed by electronicists Lawrence Casserley, Walter Prati, and Marco Vecchi and then folded back into the din--yet the saxist's grainy, concentrated melodic tendrils and patiently etched arcs are immediately recognizable.
