This is a collection of live performance of the Lucerne Festival Orchestra between 2003 and 2006. Four of five discs were previously released as individual DVDs.
2003 Debussy: La Mer/Le Martyre De Saint Sebastien/Lucerne Festival Orchestra/Claudio Abbado
2004 Mahler - Symphony No. 5 / Claudio Abbado, Lucerne Festival Orchestra
2005 Bruckner/Beethoven - Symphony No. 7, Piano Concerto No. 3, Alfred Brendel, Claudio Abbado
2006 Mahler: Symphony No. 6 [DVD Video
In addition the set includes the documentary "The History of the Lucerne Festival Orchestra" and Beethoven Piano Concerto No. 4 by Pollini, which was not available in DVD before.
The set is priced more attractively than individual DVDs, especially at Amazon Marketplace. Highly recommended.
