In a further tribute to the work of Conrad Schnitzler, Wolfgang Seidel, co-founder of Ton Steine Scherben and a friend of Schnitzler's conducted a two-part "Cassette Concert". Seidel was one of the few players Schnitzler personally authorized in his lifetime to perform this work.
Conrad Schnitzler developed the "Cassette Concert" in the 80s as a dynamic method by which to simultaneously compose and perform electronic music, one that allowed elements of structured, composed, improvised and conceptual music to be fused at will. He thereby resolved also to render performance of his music independent of his own person, claiming that a "Cassette Concert" could in principle be performed by anyone, anywhere, anytime. All that it takes to do so is several playback devices, a mixer, and a number of pre-prepared cassettes (later CDs, both supplied by Schnitzler), containing single tracks of a larger composition. The performer freely combines these single tracks, regulates the volume and equalizer settings and so, in co-authorship with Schnitzler, generates compositions that, although always identically underpinned, unfold unpredictably, as unique pieces.
