Both are conducted by Carlos Kleiber:
1.Symphony No.5 (and No.7),
with the Wiener Philharmoniker
Amazon ASIN: B00007KMOX
2. Symphonie No. 7
with the Bayrische Staatsorchester
Amazon Asin: B000EDWLY6
Although I must have heard every beat of No.5 elsewhere - you know: ta ta ta taaa - I have never had a disc of my own before. This version is neither too solemn nor too mechanic, just fine.
Why an extra disc for No.7?
It is just superior regarding the music. A Must-have I'd say.
Both SACDs are hybrid multichannel.
