This is proof that it takes two to make a beatboxing a capella rap jam go right. Jimmy is a classically trained beat boxer and Will, well he’s the freshest prince of the mic. The most impressive part of this rap session is that they create the entire beat using only their voices and an iPad app! The party gets going when The Roots join in and Big Willy kicks his verse, free-styling some of the lyrics. Watch Will Smith and Jimmy Fallon turn The Tonight Show Starring Jimmy Fallon into a concert with their beat boxing iPad cover of the old school ’80s jam by Rob Base, ‘It Takes Two’.
