"By 1965, Bley had settled on the trio format, and touring Europe revealed a warmer reception for music that employed chordless improvisations, three-way rhythmic counterpoint, un - familiar melodic constructs, and malleable song form. But there was an equally momentous conceptual change in the group’s material, as the adventurous pieces by Carla Bley were gradually being replaced by those of Paul’s new partner, Annette Peacock." - Art Lange
