«Whether in the classical music hall, the theatrical stage or film/video, Kagel’s neo-dada performances and wickedly original techniques always opens one’s eyes and ears to the pure possibilities of sounds and their production. Although this aspect of his varied productions is little known in the US, Kagel’s output as a filmmaker is tremendous. He just about made a film or video each year in the 60s and 70s, and has only begun to slow down in recent times. Films include «Antithese» (1965), «Match» (1966), «Solo» (1967), «Duo» (1967-68), «Hallelujah» (1969), «Ludwig Van» (1969), «Blue’s Blue» (1981) and «MM51 / Nosferatu» (1983).
