Moving to the phenomenal composer and friend Bill Bolcom's earlier solo piano music cracks open in me a deconstructed sense of muscle and bone: of constant disruption, fragmentation and a microscopic surveying of the impulses that punctuate my movement improvisations. The "twitch factor", as I like to call it, gets a thorough workout. It's built into the thorny sounds of the mid-century music, (or as Bill refers to it, "the post-war 'difficult' music period) characterized by an uneasy exchange between North American, South American and European composers as they all negotiated the influences of atonality and serial music.
