As part of the anniversary celebration, Eminem’s site is also hosting retrospective pieces about his major label debut. Fans can currently read an interview with SKAM2, who was famously referenced on “Stan” and did the illustrations for the Slim Shady LP’s original packaging.

“‘I even got that underground s@!% you did with Skam’ – relinked with @SKAM2official for #SSLP20 – read about the early days and his work on the Slim Shady LP on the site,” the Shady Records founder wrote on Instagram. “Capsule drops Friday. Link in bio.”

Earlier this year, Eminem dropped an expanded edition of the Slim Shady LP. The reissued version featured bonus tracks such as “Get You Mad” and “Bad Guys Always Die” as well as instrumentals and a cappella cuts.
