Dave Brubeck Surprise

During a visit to Moscow in the 80's, Dave Brubeck met the faculty and students in Moscow Conservatory. While he was improvising on a "Ei, uhnem", a Russian folk song, a young man downstage stood up to play Stéphane Grappelli-style violin jazz with him.

"This young man turned out to be a student at the conservatory. His name is Denis Kolobov and he is now a violinist of international renown." (via)
