Fresh off the release of his Pabst & Jazz mixtape, Asher Roth delivers the visuals for what is easily one of the project's most impressive cuts in "Common Knowledge." The track serves as a battle-cry of sorts for the Morrisville, Pa. native who so many wrote off as another cornball white rapper. But as you'll hear for yourself, dude can rap really well and his bars on "Common Knowledge" prove exactly that. While the video is a little too scatterbrained, it's still a fine vehicle for Roth and his rhymes. Watch it below.
