Composer/conductor Eric Whitacre says it was the video a young soloist sent him that inspired him. After holding online auditions, he wound up with 185 voices – from 12 different countries – and combined them into one “virtual choir”.
 
Here they are performing Whitacre’s original composition: “Sleep”. Pretty cool!
 

• Although the video is 9 minutes long – the song’s over around the 5 minute mark.
• Turn up the volume!
• If you maximize your screen you can read the names of the various countries represented by the choir members.
