Armed with a vigorous string section, vibrant horns that sound like they're ready for battle, and a glimmering harp, the formidable Mariachi Vargas de Tecalitlán run five generations deep—they played during the Mexican Revolution of 1910, appeared in films from Mexico's golden age of cinema in the ‘50s, and backed Linda Ronstadt in the ‘80s. Throughout their 100-plus years of existence, the caballeros deliver their powerful renditions with swooning conviction, whether son jarocho or baladas, huapangos or polkas.
