On Fathom, we hear the sound of the world mirrored back to us. An improvisational collaboration from legendary British multi-instrumentalist John Butcher, Pat Thomas on piano, Dominic Lash on double bass, and Steve Noble on drums, the four artists play generously together. Fathom is an impressive work of avant-garde jazz that’s reminiscent of the non-musical world: squeaky wheels, growing tension, a babbling brook, all winding into lush harmonies. This marks Butcher’s debut for 577 Records.
