My first choice for the Liszt B minor Sonata is Annie Fischer, she studied
under Dohnanyi, and Bartok wrote, that Dohnanyi was who opened his ears
for that musik. The mono sound is not wery good, but good enough to enjoy
the admirable playing. Moreover you get a splendid Schubert B flat major
Sonata with it. It is a Hungaroton recording.
Best regards: Janos Simonyi
