I don't know this piece very very good, but it seemed a bit messy to me. Maybe it was the second piano who played sum wrong notes to. Although, I founda performance from yu on youtube, a beethoven sonata, and i liked it more. Edit: I really liked your Shostakovitch.Editē: How difficult is this concerto? How many pages? I liked it a lot. Was it the first or the second piano concerto? (For the violinists here, there is a very nice video on youtube of Katchaturyan playing Shostakovitch violin concerto.)
The concerto is pretty difficult, at least, techinically it has a lot of challenges. In terms of Prokofiev piano concertos it's probably tied in difficulty with the first two mvts. of no. 3, but not as hard as Nos. 2 or 5. It's an amazing piece. I've attatched the public domain sheet music below. Enjoy.
I don't remember exactly how long I worked on it... I think it was a couple of months to get the whole thing memorized and up to quality. I hope one day to perform it with an orchestra. At least for now it's in my repertoire in case I'm ever called on it to be played again!
How difficult is the shostakovich?
