Colombian jazz harpist Edmar Castañeda demonstrated what the instrument is capable of in an expert’s hands on Saturday at the 11th annual Encuentro Colombian Music Festival in New York City.

If you think of the harp as a tame relic of yesteryear, check out Castañeda’s blazing fingerwork and percussive slapping on this jazz-inflected joropo, a style of music that comes from Colombia’s plains. Prepare to be amazed. ¡Arriba Colombia!
