Fischer-Dieskau's commitment to contemporary music led to his participation in first performances of works by many composers, including Benjamin Britten, Samuel Barber, Hans Werner Henze, Ernst Krenek, Witold Lutoslawski, Siegfried Matthus, Winfried Zillig, Gottfried von Einem, and Aribert Reimann. As 'the world's greatest Lieder singer' (Time Magazine), he regularly sold out concert halls all over the world until his retirement at the end of 1992. The precisely articulated accuracy of his performances, in which text and music were presented as equal partners, established enduring standards. The current widespread interest in German Romantic art song is mainly due to his efforts. Perhaps most admired as a singer of Schubert lieder, Fischer-Dieskau had, according to critic Joachim Kaiser, only one really serious competitor-- himself, as over the decades he set new standards, explored new territories, and expressed unsuspected feelings and emotions.
