Expertly dabbling with a myriad of regional Mexican folk styles with love and grace, East L.A.’s Los Lobos retrace their roots on the all-Spanish-sung La Pistola y el Corazón. On the dynamic son jarocho jam “La Guacamaya”, the Chicano heartland rockers quickly reveal their requinto prowess as they interplay with swift percussive jaranas. They follow up with a vibrant huapango huasteco on the violin-driven “Las Amarillas”—right before they candidly reveal their lovelorn norteño mastery in the slow-burning polka of “Estoy Sentado Aquí”.
