This is the first book which deals with the school of American repetitive music, also know as minimal music. The early work of La Monte Young, Terry Riley, Steve Reich and Philip Glass is discussed in the context of traditional Western music. Minimal music thus emerges as the latest stage in a development leading from Schoenberg, Webern, Stockhausen and Cage. In considering the philosophical thinking of Deleuze and Lyotard, the representatives of the so-called French ' libidinal philosophy', and of Adorno, the author examines the degree to which the 'ecstatic dimension' is present in this music or is even consciously introduced to it.
