A guitarist, formerly an all-genres studio/session musician, he has stuck mainly to a very "in the moment" brand of free improvisation since the mid 60's. Organizer of the old Company Weeks, in which improvising musicians would get together and play, often for the first (and last) time. Has collaborated with nearly every musician on the planet. Maybe even you. Co-founder (with Evan Parker and Tony Oxley) of Incus Records.
