Bradley Cooper shreds guitar when it comes to Neil Young covers. Air guitar, that is.

The Hangover actor was on The Tonight Show Starring Jimmy Fallon on Monday (his 40th birthday) to promote his latest film, American Sniper, when he performed his epic "musical" talent. 

Wearing a silly wig and moving around the stage with precision, Cooper ended up in the crowd air guitaring Down By The River over the heads of several shocked audience members.
