In this episode of Sonido Babel, we'll learn about plena: a musical genre from Puerto Rico that is played with a multitude of different instruments and deals with a plethora of topics from religion, events, recipes, advice, and even superstitions.

Nelly Ocacia and Benjamín Moldonado are both 19-year-old university students, and enjoy dancing with the Ballet Folklórico Guamanique when not studying. We caught up with them at the airport in San Juan, where they were welcoming new arrivals and seeing off departing passengers, much to the delight of travelers.

Deep in the heart of Old San Juan you can hear live salsa music playing most any night at the Nuyorican Cafe. We stepped into the alley for a breather and had a little chat with two lovely salseras to get an insider view of what brings them back to the dance floor night after night.
