This is taken from a radio broadcast, and is well known among collectors as the double bootleg CD "Live!Improvised!"; the (in)famous concert in the French cathedral which forced the Pope to ban Tangerine Dream from ever playing in cathedrals again. This version has the two encores added from a different source, not quite as good quality as the rest. aka The Tangerine Tree Volume 30.
