Got this and the two other live albums of this Berlin 1971 concert (Cousscouss de La Mauresque and Elements) decades ago. Indescribable hard free music on the edge of trance and madness. Most of the tracks of the three are one side lp . Brötz was only screaming his tenor sax here and Fred Van Hove was trying to put flesh and life to an upright. So the balance is not in the favour of the belgian pianist as regards with the noisy attacks of the two others. Here and there, come some quiter moments where you wonder to Han Bennink's sonic imagination. One of his tricks is dropping hands full of dry peas on the skins of his drums. Also Bennink kit's was full of ethnic instruments which were played everywhere on the ground of the stage or even out ! Amazing group which was augmented by the late trombone master Albert Mangelsdorff. The wildest Brötzmann's albums ever.
