Third Ear Band were a British musical group formed in London during the mid-1960s. Their line-up initially consisted of violin, cello, oboe and percussion. Most of their performances were instrumental and partly improvised. Nevertheless, their records for the Harvest label, Alchemy and Third Ear Band, achieved some popularity, after which they found some success creating soundtrack music for films.
Dave Tomlin, who had initiated free-form jazz sessions at the London Free School, began similar sessions at the UFO Club by assembling members of the audience, usually at 4am, into a free-form group playing for the, by then, exhausted dancers. The drummer, Glen Sweeney, was sometimes so carried away he had to be told that the rest of the group had finished. They became known as 'The Giant Sun Trolley'.
Members came from The Giant Sun Trolley and The People Band to create an improvised music drawing on Eastern raga forms, European folk, experimental and medieval influences. They recorded their first session in 1968 for Ron Geesin which was released under the pseudonym of The National-Balkan Ensemble on one side of a Standard Music Library disc.
Their first album, Alchemy, was released on the EMI Harvest label in 1969 and featured John Peel, the BBC disk jockey who did much to publicise the group, playing jaw harp on one track. This was followed by an eponymous second album containing four tracks, "Air", "Earth", "Fire" and "Water", which reached wider attention due to the inclusion of one track on the Harvest sampler "Picnic".
They recorded two soundtracks, the first in 1970 for an animated film by Herbert Fuchs of Abelard and Heloise (which first saw release as part of Luca Ferrari's Necromancers of the Drifting West Sonic Book in 1997) and then in 1971 for Roman Polanski's film of Macbeth. After various later incarnations and albums they finally disbanded in 1993 owing to leader and percussionist Glen Sweeney's ongoing health problems.
