There are a considerable number that can be played as solos.Thal
What's your advice for an amateur pianist who is interested in playing concertos but is not good enough to play concerts with a professional orchestra or rich enough to hire one? What about playing with Music Minus One discs? Anyone who has experience doing that? Is that a very unnatural process or does it bear some resemblance with playing with an orchestra? I suppose the other option would be to have another pianist play the orchestral part on a second piano, although this would not be a cheap option either.
