[Brahms symphonies] I think #1 a failure ..
I love Brahms 1st, particularly the Bruno Walter Columbia SO recording which was my teenage entry into it. Genuinely thrilling and thick on the ground with stirring music and melody (including the much-maligned richly flowing 'Beethoven' one in the Finale). I still find it hard to understand why some/so many find it unpalatable, to me it's a joy of a piece.
I do think Walter excels in all the symphonies, with him the music always sounds urgent/full of detail, Brahms' orchestration can sound muddy/stiff in the wrong hands, as if it's doing the job but with a bit of a struggle, that's never true with Walter. Perhaps partly to do with the sound in the older recordings, I don't know, but the music breathes and moves freely and thus is revealed at its best.
Schumann's symphonies are nice enough, but I don't see them as expressing the composer's "genius" nearly to the same extent as his solo piano music.
That perfectly sums up my feelings too.
