SLIM SHADY

It's Thursday, and that means another special archived release from Tim Westwood.

"In my entire career in the music industry, I have never found anything from a demo tape or a CD. When Jimmy played [Eminem’s demo], I said, 'Find him. Now.'” -Dr. Dre

If any rapper was going to shatter a windshield by banging their head, it would be Busta Rhymes.

In early 1999, a white rapper came out of relative obscurity and pissed off a lot of people. He was a white kid from Detroit, backed by a legend in Dr. Dre, and savvy music -industry heavyweight Jimmy Lovine.

The year 2014 marks the 18-year anniversary of Eminem's underground debut album Infinite. With almost 20 years worth of material floating around, Eminem has one of the densest musical catalogues out there.

Eminem is undoubtedly one of the best rappers of this generation, but his ability to freestyle it pretty untestable as well. His rhymes are intricate, complex, and sometimes just plain crazy. This list shows off Shady’s rare ability to spit off the cuff.
