Stunning Metronome 1st pressing that in my eyes should receive grail status because it is not just very very hard to come by but also very very good. The famous Kühn Brother are joined by Stu Martin, Volker Kriegel and Günter Lenz aka the Mad Rockers to record a fantastic progressive jazz piece. Musically it ranges from experimental jazz to beat driven jazz-rock. Gatefold cover is straight EX, vinyl has got some very light inaudible lines but would still grade it EX.
