Gloria Ríos, an American-born actress and lounge singer, is often credited with introducing rock & roll music in Mexico. Born in Texas in 1928, Ríos arrived in Mexico in 1944 and began recording in 1955 with many musicians (and their orchestras), such as Héctor Hallal, Jorge Ortega, Pablo Beltrán Ruiz, and most importantly, with Mario Patrón and his Estrellas del Ritmo. Many of her recordings were covers of songs by Bill Haley and Elvis Presley, but with Las Estrellas del Ritmo she also recorded "La mecedora" in 1956, a song composed by Mario Patrón, which was said to be the first original song of Mexican rock & roll. Ríos became very popular at the time due to her starring roles in films like "Las locuras del rock and roll" (1956) and "La rebelión de los adolescentes" (1957), but she later married Mario Patrón and in 1960 she went with him to Europe, where they stayed for many years. This caused Ríos to be quickly forgotten in Mexico, as the new golden age of rock & roll was starting there and new bands claimed to be the ones who had introduced the genre in Mexico. Ríos died in 2002 at the age of 74 years old. These orchestras soon started to lose popularity as new rock bands appeared, formed by young musicians who mostly covered American and British songs. Los Lunáticos, founded in 1956, are considered by many to be the first Mexican rock and roll band, and later other bands like Los Locos del Ritmo, Los Rebeldes del Rock, Los Teen Tops, etc. became popular. Las Mary Jets, formed in 1959, were the first all-female rock band in Mexico. Rock, as elsewhere, became tied with the youth revolt of the 1960s. Many songs are credited as being the first original Mexican rock & roll songs, amongst them: "La mecedora" (1956), written by Mario Patrón and recorded by his orchestra and Gloria Ríos. This is considered to be the first original Mexican rock song in Spanish. "Mexican rock and roll" (1956), written by Pablo Beltrán Ruiz and recorded by his orchestra, it's an instrumental piece. "Where Did You Get It?" (1957), written by José Luis Arcaráz and recorded in English by Los Lunáticos.
