A fascinating video has now appeared, showing the before, during and after of the School of Rock students performing in Roger Waters' "The Wall" concert on October 10th at the Verizon Center in Washington DC. Twenty students from the School of Rock's Ashburn, Silver Spring and Vienna locations performed the Children's Chorus from "Another Brick In The Wall."

It's a great "behind-the-scenes" look at the children's incredible experience that night!

Also on YouTube are three of their rehearsals for the show, including the first and final rehearsals.
