The Third Ear Band were one of the most interesting improvisational groups to come out of London in the late 60s. Unlike so many of their peers, they used traditional acoustic instruments rather than electric and electronic ones. Dave Tomlin was interested in free form Jazz, and initiated sessions of this music at the London Free School, and later at the UFO club. He was soon joined by drummer and percussionist Glen Sweeney, and the result became known as ‘The Giant Sun Trolley’. Later they combined with members of another free improvisational group to become the Third Ear Band, whose first music was recorded with legendary composer and arranger Ron Geesin.
