Who is C-Diddy?
He is a god amongst men. A titan amongst mere mortals. He is the first World Air Guitar Champion from the U.S. of A. He is C-Diddy.
I strongly, strongly, STRONGLY suggest that you rent/watch Air Guitar Nation completely spoiler free (I think it's the only way you'll get the full force of its impact), but if you must get a taste of the pudding before you eat the pie, then witness C-Diddy in all his glorious splendor.
