Shaun White -- Shreds Guitars Too ... Rock Band Jams in DC

It's official, Shaun White dominates everything he touches -- snowboards, skateboards, surfboards, and now electric guitars ... and we got video proof last night.

If you haven't heard ... Shaun plays lead guitar in a band called Bad Things -- and last night their summer tour stopped at DC9 in Washington, DC.

The Olympic gold medalist had a Gibson Les Paul sunburst ax slung over his shoulder during the gig ... and while he's not Slash or Stevie Ray Vaughan just yet ... dude ripped off a decent solo.

Next up for Shaun -- the World Cup of Pottery!
