Betto Arcos is back with tracks from all over Mexico. “Buen Camino” by Laura Murcia celebrates departures, a lost friend, and the Caribbean coastal sounds of Colombia. “Zapatea” from El Monte Adentro is a foot-tapping trip through modern and traditional sounds of Jalapa. And “Estero” by Renee Mooi takes us to the moonlit wetlands of the Costa Chica of Guerrero.
