A whole chapter of recent musical history must be rewritten: the second half of this century is now unthinkable without Scelsi... He has inaugurated a completely new way of making music, hitherto unknown in the West. In the early fifties, there were few alternatives to serialism's strait jacket that did not lead back to the past. Then, toward 1960–61, came the shock of the discovery of Ligeti's Apparitions and Atmosphères. There were few people at the time who knew that Friedrich Cerha, in his orchestral cycle Spiegel, had already reached rather similar results, and nobody knew that there was a composer who had followed the same path even years before, and in a far more radical way: Giacinto Scelsi himself.
