Two sessions previously assumed either lost or unrecorded, by Henry Lowther’s and Lyn Dobson’s mid-sixties groups. Considered one of the missing links in the development of British free-form jazz. The Group Sounds Four session includes Jack Bruce, who contributes an original composition never otherwise recorded. Also features Ron Rubin, Ken McCarthy and Jon Hiseman.
