The MIDI Mafia is a music production duo consisting of American Bruce Waynne (born Waynne Nugent) from Brooklyn, New York and Canadian Dirty Swift (born Kevin Risto) from Ottawa, Ontario. Together as Midi Mafia since 2003, they are most notable for their production of 50 Cent's number-one single "21 Questions". The MIDI Mafia has also produced for artists such as Sha Stimuli (the single "Clap At Ya"), Capone-N-Noreaga ("Yes Sir"), Bravehearts, Gemma Fox, Jean Grae, Talib Kweli, Young Buck, Nelly, Miri Ben-Ari, Lloyd Banks and Tamia.
Bruce Waynne met Dirty Swift at Makin' Records Studio in Brooklyn, NY, while working on a project for Bad Seed. At the time, Swift was the in house engineer/beat maker for the project, while Bruce pitched beats and helped compose and perform choruses for Bad Seed.
The duo officially began working together after attending a meeting with manager Tony Perez, who suggested that Bruce and Swift would make a good musical team. They began to hold meetings with different A&R representatives and did spec work for various people, including Sylvia Rhone, who was the president of Elektra Records at the time.
In 2002 Dino Devalie, who was preparing to sign 50 Cent to his label, approached The MIDI Mafia about using some of their beats for 50 Cent’s debut record, Get Rich or Die Tryin'. MIDI Mafia agreed, and though 50 Cent ended up signing to Interscope Records instead, their beats were used for the song "21 Questions", which was featured on Get Rich or Die Tryin'.
