When we first met Jadon Woodard, he was the central subject of our documentary Street Dreams. Jadon is one of the brave souls selling his music by hand, freestyling on New York’s subway cars and trading CDs for dollars. Since then, he’s started to blow up, winning a Jack Daniels competition, giving TED talks, and opening for artists like D.R.A.M.

Jadon is definitely on a roll, but he hasn’t lost his powers of improvisation—that much was clear when he stopped by our place during SXSW. He took the first beat we played him—DJ Screw’s “June 27th”—and went to work. Watch Jadon’s verse above, and check out the rest of our SXSW videos here.
