Query: Excellent Performance

Four stars instead of five only because of slightly dated sound.I've never been quite as enthralled with Bernstein's Mahler as many others seem to be.However, when he's good, he's good. And he certainly is good in this performance.I've been partial to the Solti recording for years because of the magnificent roster of Decca's opera singers who were recruited for the recording, as well as for the superior sound (except for the occasionally off-balance dubbed organ).Bernstein simply gets inside Mahler here better than Solti ever could have. Solti is all external verticality, as was often his wont. Bernstein is internal linearity.And Sony has even done a good job cleaning up what was always problematic sound. The sonics aren't "modern day" (what the heck was wrong with Columbia in those days?), but they certainly are acceptable to modern ears.I've listened and I've been converted. I'm now a Lennie fan. That is, for this recording.
