Method Man & Redman, are an American hip hop duo, composed of East Coast rappers Method Man and Redman. They are signed to Def Jam Recordings as both solo artists and as a collective. While they had been collaborating since 1994, it was not until 1999 that they released a full-length collaborative effort, Blackout!. The follow-up album, Blackout! 2, was released in 2009. Method Man often gives a shout out to Redman on tracks that do not feature Redman; this usually comes in the form of "What up, Doc!" referring to Redman's alias "Funk Doctor Spock". In 2001, they starred alongside each other in the cult classic stoner film How High. In 2004, the duo also starred in a short-lived Fox sitcom, titled Method & Red, however they later disowned the series due to lack of creative control.
