For much of his life, Otto Klemperer carried a note written by his hero Gustav Mahler, in which the composer praised the young Klemperer as 'an outstanding musician [...] predestined for the career of a conductor.' Klemperer's interpretations of Mahler's work, famous for their 'big outlines' and 'rock-like rhythms' (Musical Times) became world-famous. This collection showcases Klemperer's Mahler, including works such as the Ninth Symphony and Das Lied von der Erde.
