[Machine Translation] The Kuhn brothers Joachim and Rolf Kuhn burst between jazz and rock in this unique work. This is a piece that represents the BYG - Hamburg recording period and captures the fervor of European avant-garde jazz of the 1970s. The brothers' tense dialogue intertwines with the sharp guitars of Volker Kriegel and others. Commentary included. Recorded February 17 and 18, 1969 in Hamburg / Original release date: 1969
