"This is the encore (the following year) of their Debussy 'Afternoon of a Faun' performance. Equally Brilliant!
I had no idea how they memorize all that music. I was SO curious that I looked up one of the players on Facebook (a cellist). She told me that they worked on it all year. They learned the music as an orchestra first in a traditional way. Then while they were choreographing, they had the score on a screen above the stage so that players could look when necessary. And eventually, they took away the screen. This is an amazing feat!"
