Mr. Porter has been played on NTS shows including The Hot Selection, with Calls Feat. Jill Scott first played on 5 January 2014.

Denaun Porter (born December 7, 1978 in Detroit, Michigan), known by the stage name Kon Artis, or the production title Mr. Porter, is a rapper and producer, who rose to fame as an original member of Eminem's Detroit rap collective D12.

Denaun Porter started his rap career at a young age, when his original dream of playing professional basketball in the NBA was shattered after receiving gun wounds to his leg. Porter founded the rap duo Da Brigade before being approached by late rapper Proof to start the hip hop group now known as D12. After Eminem rose to prominence, he signed Kon Artis along with the rest of D12 to Shady Records. While on the label they have released two albums, with a third in production.

Along with a rapping career, Porter also doubles as a very successful hip hop music producer under the alias Mr. Porter. He has also dabbled in singing, performing the chorus of "Look at Me Now " from Young Buck's debut album, Straight Outta Ca$hville , demonstrating a surprising vocal range. Porter proved to be a natural on Buck's single, and could have easily been mistaken as a veteran RnB singer. He has produced for the likes of Snoop Dogg, Obie Trice, Eminem, Busta Rhymes, Method Man and Young Buck. He created the beat heard in the highly successful single " P.I.M.P. ", for label mate 50 Cent, and followed it up with another smash hit " Stunt 101 " for the rap group G-Unit.
