Leonard Bernstein, Israel Philharmonic, Christa Ludwig, Rene Kollo - Mahler: Das Lied von Der Erde (2007) [SACD]

Leonard Bernstein’s first complete cycle of the Mahler symphonies, in the Japanese stereo/multichannel releases of what were originally 3-channel recordings.
Mahler was terrified of the “curse of the 9th” – that both Beethoven and Bruckner had died after composing their 9th Symphonies. Accordingly instead of a numbered symphony, after the 8th he wrote this “symphony of songs” in 6 movements. It contains some of Mahler’s loveliest vocal writing, especially in the lengthy farewell at the final movement.
For those who want to keep their Mahler Symphonies straight, a helpful guide.
If you want Bernstein on Mahler, there’s no better place than his televised “Young People’s Concert” on Mahler.
