This rare audiovisual footage presents Klaus Tennstedt at the height of his very special relationship with the Boston Symphony Orchestra during his prime recording period. Joyous Mozart is combined with evocative Mahler, both performed with the greatest sensitivity and conviction. The ICA Classics Legacy series represents an historic account of performances by some of the world’s greatest artists. This DVD features only the second public release of a full-length symphonic work with the Boston Symphony Orchestra under Klaus Tennstedt and the third DVD available with this mighty conductor. While the material has been restored using the greatest care and state-of-the-art techniques, certain visual artefacts and distortions remain in some instances due to the age of the film. Despite this, it remains of exceptional musical interest and historic value and is released here for the first time on DVD.
