Thanks, Erik.
Jansons left three recordings of the work with Oslo Philharmonic Orchestra, RCO, and this one with Bavarian Radio Symphony. All are excellent, but aided in great measure by the rich, well blended sonority of the orchestra and the mezzo soprano Nathalie Stutzmann's great singing in IV. (Nietzsche movement), the BRSO recording is the one to choose.
I own the previous CD release that was sold in Europe and limited to the BRSO subscribers. I am sure BR Klassik remastered the recording as they had done to most of their reissues with increased dynamic range, details, and clarity.
