Betto is back with 3 new tracks for us showcasing traditional folklore sounds in contemporary ways. Ernesto Anaya plays over 30 instruments and brings that flash in “El Relámpago.” Valeria Rojas of the supergroup Los Folkloristas has a new solo single “La Pajarera.” Xinto Stevenz found his stage name while living in Los Angeles for a short stint, and then returned to Mexico City where he plays the guitarra de son, the traditional instrument of Veracruz on “Sueño.”
