Sir Georg Solti studied piano with Béla Bartók at the Franz Liszt Conservatory. In the following excellent documentary, Solti describes this and many other experiences during his rich and full life.
Solti was a fascinating person and I find way of making music perfectly suited for the music of Bartók. This set has almost all of his recordings.
However, Solti was also an excellent pianist and this recording of Bartók’s Sonata for Two Pianos and Percussion Murray Perahia is also a must hear.
