NB: A very useful website for Bach transcriptions in general (it was very useful for compiling this list) is: http://www.bach-cantatas.com/NVD/PT.htm.  

This list includes the works of transcribers from the Russian Empire, Russian Republic, RSFSR, USSR, the former-USSR states, and those musicians in the artistic careers of whom the Russian/Soviet piano school played an important role. No potential offense or political implications were intended with the inclusion of any musicians currently active in any of the countries which were former USSR republics who had created their transcriptions after the fall of the USSR; the inclusion was prompted by the desire to make this compilation as comprehensive as possible, including those musicians who were in some way associated with the former USSR.
