There is a large Barbirolli box that has been released, with many 78 recordings.
My impressions of J.B. Are from his stereo recordings, in his last decade or so.
His Mahler is impressive, but ultimately just to slow and world weary for me. I like the Sibelius stereo set with the Halle Orchestra, but the Orchestral deficiencies are wearying. It would be interesting to hear the younger J.B.
Re Curentzis, I admit that I am one of those that is off put by his relentless P.R. Machine. The one recording of his that I did stream, Tchaikovsky 6, didn’t begin to live up to the hype.
I second the comments about Barenboim as a Furtwangler wanna be. The young D.B. was so phenomenally talented. It just seems weird to want to ape another musician to the extent that he has, and to alter the natural growth curve that he may otherwise have experienced. Furtwangler make it seem as though he was playing the Orchestra like an individual instrument, exercising complete command, apparently able to manipulate the musicians to follow him wherever he went. I think it was that improvisatory feel that D.B. the Pianist wanted to bring to his conducting
