With “studio reihe neuer musik”, WERGO created a trademark of advanced contemporary music in the Sixties of the past century already. Some of these important recordings have not been available on CD up to now. On the occasion of its anniversary, the label now releases the gems from the early days of its 50-year history: highlights of 20th-century music history which have lost nothing of their topicality and liveliness, in standard-setting recordings of great performers and audiophile sound quality.

The works by Wolff recorded on this CD by the legendary pianists David Tudor and Frederic Rzewski and their fellow musicians David Behrman, John Nash and Gordon Mumma are determined by chance. Wolff's works are characterized by the challenges he assigns to the performers: the responsible use of freedom.
