Anyone can play guitar, but it takes true skill to rock out on air guitar, as Bradley Cooper proved.

"It's so meaningless," Cooper admitted with a laugh about having memorized the number on air guitar.

He then put on quite a show throughout the lengthy solo, even making his way into the audience at one point.
