EminemAn entire compilation, filled with rarities from Eminem, made its way to the blogosophere this week, following the leak of an old freestyle in which the Detroit rapper spit over 50 Cent’s 2007 beat for “I Get Money.”

The freestyle featured Em in his old form, rather than the uplifting sober version seen on his latest, multi-platinum album, Recovery. And the leaked mixtape seems to be more of that old Eminem we’ve been accustomed to.

The mixtape, titled Straight From The Vault and hosted by StudioLeaks.info, features 10 previously unreleased tracks from Em, as well as features from Obie Trice, B.o.B. and D12.

According to reports, the tracks were leaked one-by-one, anonymously to an Internet message board, and then later packaged into the mixtape that’s currently being circulated.

At press time, it’s unclear when these tracks were recorded.

However, from what we heard on the “I Get Money” freestyle, it’s seem clear that they date back before his pre-comeback and his re-emergence as a sober Eminem, who released Relapse in 2009, followed by Recovery in 2010.

In addition to the recent leaks, Em’s camp recently unleashed a new track, titled “2.0 Boys,” featuring the latest additions to his Shady Records roster — Slaughterhouse and Yelawolf.
