Last night on the Tonight Show with Jimmy Fallon, guest Will Smith and host Jimmy Fallon delighted viewers with their beatboxing/technology mashup skills by performing “It Takes Two” with just their voices and an iPad.

Fallon, self-dubbing himself a “classically trained beatboxer,” brought out his iPad to demonstrate a looper app which allows you to put down a few tracks on top of each other, known as recorded layering. Will Smith and “J-Fal” laid down the parts to rap “It Takes Two” by Rob Base and DJ E-Z Rock. Tonight Show house band The Roots joined in after a few measures.
