Tim Westwood has reached into his stash for throwback Thursday and shared the full audio for a previously unreleased freestyle featuring Eminem and Proof. Em has a history of stopping through Westwood's spot over the years and showcasing his exceptional lyricism. This particular freestyle with Proof took place around the time his major label debut album, The Slim Shady LP, dropped. The two rappers don't disappoint, with Eminem stitching together lyrics from classic #deepcuts like "Any Man," "Bad Influence," and more. Proof also comes correct over the beat for Nas' "Hate Me Now. This should serve as a reminder of how great their chemistry was on the microphone. R.I.P. Proof. Check out the full freestyle above. You can also download it here.
