Acoustic duo Anielle Reid and Matthew Brookshire (playing together as Boy Girl Banjo) take the TED stage to perform their original song "Dead Romance," weaving together the sounds of Americana folk music and modern pop.

Folk musician and storyteller David Holt plays the banjo and shares photographs and old wisdom from the Appalachian Mountains. He also demonstrates some unusual instruments like the mouth bow -- and a surprising electric drum kit he calls "thunderwear."
