Eminem and his longtime manager Paul Rosenberg are celebrating 15 years of Shady Records, the label the two Detroit natives co-founded in 1999 prior to Em's debut studio album, The Slim Shady LP. The company has gone on to have massive success with marquee artists like 50 Cent, Yelawolf, Slaughterhouse, and of course Eminem, which is highlighted on their new compilation album, Shady XV. The project features a full disc of new material from the Shady roster, as well as a second disc of greatest hits.

What does the next 15 years of Shady Records entail? Based on Eminem's reaction in the teaser above for the upcoming documentary, Not Afraid: The Shady Records Story, a whole lot more craziness from Slim Shady and crew.

Stay tuned for the full Shady Records documentary, which premieres on Complex TV in December. Shady XV is available for purchase on iTunes.
