Watch Bradley Cooper shred air guitar for Jimmy Fallon

Bradley Cooper's best instrument is clearly air guitar.

On "The Tonight Show Starring Jimmy Fallon," the "American Sniper" actor took a moment to show off his skills, shredding Neil Young's solo from "Down by the River."

Wearing a special birthday visor/afro outfit given to him by Fallon, the actor strutted throughout the stage, constantly asking the volume to be turned up. He wailed for minutes on end, even taking the solo out into the audience.

Cooper's appearance on the show Monday also coincided with his 40th birthday. What better way to celebrate than this?
