It is a few minutes before rehearsal.
A tall, slender man, dressed in a loose cardigan, is checking the stage of the concert hall where he will perform a Debussy cello sonata that night. The hair at the back of his head sticks out slightly, as if he has been napping earlier.
But the world-renowned cellist, Yo-Yo Ma, is very much alert. After a careful inspection of the hall, he invites his fellow performer, Vadim Sakharov, to the stage. Soon after they start playing the piece together, Ma suddenly stands up and jumps off the stage.
