In February 2007 , the Choir also appeared as performers in the 79th Academy Awards , producing sound effects to a collection of different film clips in a piece called '' Elements and Motion '' . A video of these movie clips was shown behind the forty person choir , as they performed in Kodak Theater . Although much praise was given to this particular performance , it has received some criticism of not reaching the high expectations set in any Academy Award festival
