Imagine the things that Tim Westwood has in his house? Because that guy is always unearthing some cool, mostly forgotten gems by your favorite rappers.

The latest example of this came last night, when the legendary DJ released some previously unreleased footage of Kanye West freestyling for damn near 15 mins on his show all the way back in 2005. (This was Late Registration-era Kanye.)

What makes this freestyle particularly cool is the fact that Mr. West is rhyming over beats that he has never rapped to: He spit over The Game’s “Dreams,” Jay-Z’ “Encore” and Common’s “The Corner.”

Please take 15 minutes to listen, cause THIS SH*T RIGHT HERE…HARD.
