P.Tchaikovsky. The Variations on a Rococo Theme for cello and orchestra 

,,

Mr Bulov，您的琴技精堪非凡，惊人的演奏，奇特的精彩。表情优雅，多姿多彩，激情奔飛，風彩騙騙，深感动人。此協奏曲，旋律音色演奏的極其透明，清晰饱滿。特別一段独奏，旋律音色演奏的特別悠揚抒情甜美，簡直太迷人了。您的出色精彩华丽的演奏，让人沉浸在太美妙及优美动听的情深中而深深的陶醉。,,谢谢您的精彩演奏，From Hong Kong。

Bernard Tremblay . I have it on my youtube chanell check it out.

Bernard Tremblay this version has less variations and an ugly armonic cut in the end, and the orders of the movements are not in the right position as Tchaikovsky put in the past.. this version with Bulzov, was modificated by great russian cellist Wilheim Fitzenhagen who was teacher and solist that time. Tchaikowsky was quite angry when he fond out about the modifications that Fitzenhagen did, he was away that time in Switzerland.

Where can I found sheet music from Alexander Buzlov version? Please give me one reference about.
