I have Brunswick
90227/9 Beethoven. Sonata, op. 53. Waldstein
90259/60 Bethoven. Sonata, op. 26
I can't find the Hammerklavier, but it was in a later album BP-something, in
beautiful laminated pressings.
85015/6 Beethoven. Piano Sonata, op. 27 # 2, Moonlight
85029/31 Beethoven. Piano Sonata, op. 13. Pathetique
DGG acoustic. Polydor pressings
66033/5 Beethoven. Sonata, op. 57
66036/38 Beethoven. Sonata, op. 53. Waldstein
66176/7 Beethoven. Sonata, op. 13. Pathetique
69815/8 Beethoven. Piano Concerto 1
As DGG pressings came available, I got rid of my usually-noisier Brunswicks,
so there may have been more. Was there a Bach Chorale-Preludes disc?
Short of going to the catalogs, that's what I can supply on this topic.
