Seminal figures in the evolution of free or nonidiomatic improvisation, guitarist Derek Bailey and percussionist/pocket trumpeter John Stevens are heard in a 1989 London performance vividly captured by Michael Gerzon at The Duke of Wellington, their restless and enthusiastic interplay shifting from angular invention to lyrical reflection in a compelling document of their remarkable rapport.

A significant release from the history of the Detail trio of Frode Gjerstad on reeds, John Stevens on drums, and Johnny Dyani on bass, recorded at the Red Seahouses in Norway in 1938 during Detail's first trio tour, a smoking set of free jazz showing the power of these innovative players around the time of their first album, "Backwards and Forwards".

Live recordings from 1973-74 from the trio of drummer John Stevens, guitarist Derek Bailey, and saxophonist Trevor Watts, dynamic works performed "impromptu" with a wealth of ideas as these innovators demonstrate the skills that helped define them as masterful players.

Norwegian saxophonist Frode Gjerstad recorded this wonderful, spirited meeting with his friend, the late, great drummer and conceptualist John Stevens in 1994.
