Around Latin America, Colombia is known as the heartland of cumbia, one of the most-listened-to styles in the Americas. But in Colombia itself, cumbia's popularity came and went in the 60s and 70s. Until now. A new generation of young Colombians are digging into Afro-Colombian roots music as a rich source for modern musical fusions. We speak with some of the hottest young Colombian artists in this movement today, including Systema Solar, Bomba Estereo, ChocQuibTown, and many more. Plus, we take a look at the neo-cumbia renaissance sweeping dance floors around the world, and take an eye to the music's new-found global vogue among blogging hipsters and digital beatsmiths.
