Felix Contreras and Jasmine Garsd—hosts of NPR's ongoing series on Latin alternative music—recently stopped by for an episode of Weekend Edition to discuss the history and far-flung influence of cumbia, a syncopated style of music and dance that ranges from the traditional to the Top 40 (you can hear cumbia's influence on Macklemore and Ryan Lewis' chart-topping "Thrift Shop.) You can listen to the piece here, along with a handful of song selections that illustrate the various flavors of cumbia.
