I know we've had a discussion somewhere about how Film Music differs from Classical Music, but I can't remember where (please tell me if you know). 

I might've mentioned the film, "Memoirs of a Geisha" (2005) - a fabulous story, but not sure if I talked about who played in the soundtrack. 

John Williams did the score, the Violin & Cello solos were played by Itzhak Perlman and Yo-Yo Ma! 

"Sayuri's Theme" is just the 1st... the rest of the soundtrack is gorgeous!

I couldn't find one soundtrack video with the tracks timestamped, so here's the video playlist to hear them in the other tracks (Soundtrack Central) -

Yo-Yo Ma & John Williams on the Tonight Show with Jay Leno!  (PRMmancini007) 

Memoirs of a Geisha is not the only film that Itzhak Perlman & Yo-Yo Ma have played scores for!
