Marcus Gloster, better known by his stage name Black Cobain is an American rapper signed to The Board Administration. He is most notably recognized for his collaboration on the Wale track "4 AM" and as the opening act of Wale's 2011-2012 53-city "Ambition" tour.

Black Cobain performed the local circuit and various open mics within the DC, Maryland, and Virginia areas to garner attention and heighten awareness of his brand. After a solid run releasing freestyles and frequenting local performance venues, Black Cobain released his debut mixtape, Now or Never. Now or Never focused on his transition into adulthood and the perils of inner city life.

His 2011 mixtape, Young, Gifted & Black, hosted by Rocksmith Tokyo, possessed features from Wale, Stalley, and featured production from Tone P and 88-Keys. Young, Gifted, & Black is regarded by many as his most solid work to date and shows his full emergence from local act to national contender and someone to know.

In August 2012, Black Cobain toured as an official opener for the Meek Mill Dreams and Nightmares Tour. He is also featured on Wale's track Bag of Money Remix alongside Rick Ross, Lil Wayne, Yo Gotti, T-Pain, French Montana, and Omarion.
