Don’t worry. I’m not going to try to cover all of them. That would be the work of a lifetime! I’d just like to mention three I love who epitomize a kind of gentleness — and strength — as well as clarity in their playing.
There is my mother’s favorite: Alfred Brendel, probably one of the greatest pianists of all time.
Then there is my favorite Viennese pianist, whom I’ve written about here before, Helmut Deutsch, who usually works with singers, most often Jonas Kaufmann. (Friends in the meantime know that I go to lieder recitals mainly to hear Deutsch play and suggest recitals accordingly.) I’ve put links to the previous posts about Deutsch below.
Recently, I rediscovered one of my first (pianist) loves: Walter Klien. I have, still on cassette, a recording that includes this Brahms waltz, one of the most soothing and uplifting pieces of music I know, as well as Schumann’s “Kinderszenen”, which I can’t hear without thinking of Judy Davis, Sam Neill, and “My Brilliant Career”. I didn’t know until today that Klien also worked with some of the great singers of his age. Here is a recording of Richard Strauss’s “Die Nacht” he made with the renowned German bass-baritone, Hans Hotter.
And so a bit of music and a homage to three great Austrian pianists.
