Eminem isn't slowing down in his middle age. According to Hip Hop Vibe, Shady is working on a new solo album called Roots, which will drop in 2015.

He is expected to officially announce the album at the Grammys, which air on February 8th. Dr. Dre and Xzibit will be among the featured artists on what will be 42-year olds' ninth solo studio album.

In 2014, Eminem dropped the Shady Records compilation Shady XV, and in 2013 he released the solo effort The Marshall Mathers LP 2.

We will have more details on this development when they become available.
