East L.A.’s Las Cafeteras are part of a new wave of young bands that blend their urban outlook and political activism with the traditions of son jarocho music—a genre from Veracruz, Mexico.

A post-performance discussion with NPR’s Betto Arcos and Cesar Castro of Fandango Sin Fronteras explores the roots of their style. More information.
