In my wanderings through the Internet, I came across a documentary on the life of Schubert presented by pianist András Schiff. I enjoyed hearing Schiff’s perspectives on Schubert’s life and works, which to me lifted it from the realm of typical documentary fare. Schiff’s illustrative playing on a rather wonderful Bösendorfer make it that much better.
The Royal College of Music has made three of Schiff’s master classes available on their YouTube channel. The classes are on Schumann, Schubert, and Haydn.
