Beton-Studie/Zeitmass Für Fünf Holzbläser/Klavierstuck XI

A collection of some of Karlheinz Stockhausen's earliest work, including his earliest piece of musique concrete, Beton-Studie (aka 'Etude'), written by the experimental composer in 1952-53 at Pierre Schaeffer's studio at the RTF in Paris. Until 1992 the piece was believed to have been lost. This LP also includes the celebrated Zeitmass (1955), and Klavierstück XI, parts I-IV (1956), both of which helped to cement Stockhausen's role as one of the leading German composers of the 20th century. Zeitmass performed by Arthur Gleghorn, Donald Muggeridge, Donald Leake, Donald Christlieb and William Ulyate in Los Angeles, 1958. Klavierstück XI performed by David Tudor in Köln, 1958.
