Last week, with the release of the Shady Records compilation Shady XV, Eminem gave fans a previously unreleased version of "Lose Yourself." If that wasn't enough, don't worry: On Monday (December 1), we got some more rare Slim Shady rhymes.

Back before Marshall became one of the biggest rappers out, only appearing on the biggest platforms, he was a hungry, underground MC trying to prove himself. And that's exactly what we hear in this freestyle from 1997 at Baruch College's radio station in New York City, brought to light by HipHopDX.

"Eminem comes in somewhat shy or just cool and I thought [his manager] Paul [Rosenberg] was his bodyguard because he was a big dude," DJ Sincere, who hosted the station's Solo Vibes radio, said. "Needless to say, Em killed it with a battle style that was so sharp, besides his flow and delivery, how he spit, what he spit, and how everyone in the room was so impressed."

Not that hearing that is a surprise, all these years later.

The two-part December 9, 1997 session brought Eminem and rapper A.L. together, as the two traded bars over a variety of beats, including Diamond D's "Soul on Ice" remix. Some of the raps may be new to you, while others you may have heard appeared in other places: There's a verse from "As the World Turns," off of The Slim Shady LP; one from "3hree6ix5ive," a "Stan"-immortalized collaboration with Skam; one from a freestyle that he did in 1998 on "The Wake Up Show."
