Old School rappers have been bringing it back in droves with comeback albums lately. Rakim, Slick Rick, and Run DMC are just some of the artists who have dropped comebacks in the past few years, but now add to that Masta Ace.

Ace’s last album, Sittin on Chrome came more than five years ago, but now he’s back, and he’s dropped the Inc. Ace’s new album Disposable Arts is scheduled for an October 30 release. The album is a concept album which chronicles a man getting out of jail, off the streets and into hip-hop school, The Institute of Disposable Arts. Hip-hop fans will remember the concept album format from Prince Paul’s A Prince Among Thieves.

The new album will feature a long guest line-up, including the likes of J-Ro, Greg Nice, MC Paul Barman, King T and Rah Digga. The record will also feature a reply track to Boogieman, who reportedly ripped Ace at this summer’s Lyricist Lounge tour.
