Members came from The Giant Sun Trolley and The People Band to create an improvised music drawing on Easternraga 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 actual album, Alchemy, was released on the EMIHarvestlabel in 1969, (featuring John Peel playing jaw harp on one track), followed by Air, Earth, Fire, Water (aka Elements) in 1970. 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.
