Beyonce rehearsing backstage for American Idol Finale

Beyonce is amazing! This is how it's done.

From Jay-Z:

Sometimes you need perspective. You’ve been right in front of greatness so often that you need to step back and see it again for the first time. This is the dressing room rehearsal for American Idol. NO MICROPHONE. No effects. – Andy WarHOV.
