By 1926, the Mexican Revolution had waned, and the Cristero War was just erupting. That same year, Cirilo Marmolejo and his Mariachi Coculense—by then residents of Mexico’s capital city—became the second mariachi in history to make phonograph recordings. These 78 rpm records used the latest “electric” technology, which Discos Victor had recently installed in its Mexico City studios. This new system was radically superior to any previous technology, and here the guitarrón may be heard prominently for the first time.
