Preston Reed and Usman Riaz:
A young guitarist meets his hero
Usman Riaz is a 21-year-old whiz at the percussive guitar, a style he learned to play by watching his heroes on YouTube. The TED Fellow plays onstage at TEDGlobal 2012 — followed by a jawdropping solo from the master of percussive guitar, Preston Reed. And watch these two guitarists take on a very spur-of-the-moment improv.
