Accompaniment Difficulty Level

[Bethelbass1]

One quick question.
What is the difficulty level of the Koussevitzky Bass Concerto's piano part? Also, is there an online source that rates accompaniment parts? That would be a great resource.

I have played the Koussevitzky Concerto with several accompanists. Most have commented that the part is very difficult. A few have even commented on how poorly the piano part in the International edition is arranged. As for a difficulty level, I don’t have one or know of a site that rates the parts. Hope this helps.
