[Rimsky-Korsakov Conservatory]

I don't know if we are talking about the same music conservatory, but if I'm not wrong the name of the Music Conservatory and Academy of Art of St. Petersburg before 1920 was Rimsky-Korsakov Conservatory ,I think that it's still the actual name...you can read a short article here: http://en.wikipedia.org/wiki/Saint_Petersburg_Conservatory
