I played a solo piano tranposed version of the aforesaid concerto at a local concert some months ago and the audience reaction was fantastic with a large number of people approaching me for more information about him.
Did you just play the solo part with the orchestral parts filled in? I am curious as to how someone would do a transcription of it. It has rather involved orchestral parts. All three of his piano concertos are like that.
Balakirev Toccata
This looks like a Thal area.Depends how unknown you want to go - CPE Bach (or any Bach son), Clementi, Reger? Sort of known but not widely played.
i just uploaded some liner notes as part of my research for a taneyev work i just started to learn. He is probably the most important and influential teacher, composer and pianist most people have either never heard of or have forgotten.
I have heard of him for his teachin (pupils included Scriabin and Rachmaninoff - at the same time!), but must confess to not having heard or played any of his own works. I have a collection in my pdf collection.What one are you doing? The P&F?
