I'm unfamiliar with the following DSCH symphonies, which my music store has on offer in these versions. If you're familiar with these, or have some idea about what to expect, I'd appreciate hearing about it: Symphonies 11 and 12 (plus other works). Neeme Jarvi/Gothenburg Symphony Orchestra (DGrammophon double) Symphonies 6 & 12. Mravinsky/Leningrad Philharmonic Orchestra live performances dated 1955 and 1962 (Praga/Harmonia Mundi) Thanks in advance. Bert Bailey, in Ottawa
