This is a live recording from the early 80s from the Palace of the Republic in East Berlin. Who knows Force Majeure and Tangram already, will experience at least an equivalent work here. Actually, even better !!! Wrongly this album is something unknown, as it was not then produced because of its eastern background on a known record label. At that time the East German broadcasters participated in the concert. Super-sound, because the best technology. On wiretapping, the comrades have well understood.
