On December 24th, 2006 the great contemporary composer, performer, and film director Mauricio Kagel celebrates his seventy-fifth birthday. In honor of this event, Winter & Winter publishes in a special hardcover package three most important, hand-picked, historic works produced by WDR, an extraordinary German radio station which is most important for the realization of Kagel"s works in the last fifty years: the Mauricio Kagel Edition, in a limited numbered disc set. The first CD presents the historic solo performance of Pandorasbox for bandoneon, created and recorded by Mauricio Kagel in 1965; Tango Alemán, sung by Mauricio Kagel in 1978, and Bestiarium, an "animal concert for humans" created in 1967 by recording whistles imitating birds and other animals. In 1969 Mauricio Kagel and WDR producer Klaus Schöning started to create acoustic art. The first project called, Aufnahmezustand I [state of recording], is a recording, manipulation, and collage of sounds, noises, music, and conversations made in a radio studio. In the DVD directed by Mauricio Kagel, we are in the year 1970 and Beethoven returns to see his hometown Bonn and his house in the year of his 200th birthday. A wondrous 35mm film shot in black and white tells from the perspective of Ludwig van his experiences in the twentieth century.
