After Avándaro: the black hole of the mexican rock  A part of the early history of Mexican rock (a more complete history in: The beginning (1955-1975). Gallery of some Mexican groups of 1960 at 1965 here.   The Black Jeans, later the Camisas Negras and the first and unique LP According to those who know about rock in Mexico, its history began when the Black Jeans, formed by Casar (Costa) Roel, Diego de Cossio, Juan Manuel Cossio, Javier de la Cueva and Carlos Loftus; released a single in 1960 on the Peerless label with two songs: "La Batalla de Jericó" y "La Cucaracha." Later on they hispanicized the name to Camisas Negras and an LP was released. The exit of Cesar Costa to become a soloist was the end of the group, which disintegrated with its members leaving to other formations. But some bands like Pepe y sus Locos del Ritmo were founded in 1958, integrated initially by Antonio de la Villa, José Negrete, Alberto Figueroa, Alvaro González and Pepe del Río; they won the competition of "The Fan's International Hour" on Mexican television Channel 2 , thanks in part to the cheerleaders, who were captained by Luis "Palillo" Rodríguez, leader of the football team Pumas de la Universidad. TThe first prize was a trip to New York to compete on Ted Mack's show where they finished in second place.   Pepe y sus Locos del Ritmo  Between December of 1958 and January of 1959 an LP was recorded for Dimsa, but its release was delayed until 1960, when it had been proven that rock and roll was good business. By then they were simply called Los Locos del Ritmo and comprised of Toño de la Villa, Jesus González, José Negrete, Rafael Acosta and Alvaro González, plus invited musicians like Alberto Figueroa and "The Doctor". This recording was the beginning of a music by kids for kids, for in previous years, "rock" songs had been sung by pop singers such as Gloria Ríos, who covered "El Relojito," "Hotel de Corazones Rotos" y "La Mecedora," all Spanish-language covers of songs recorded by Elvis Presley and Bill Haley and the Comets. Gloria Ríos, singer and vedette    Additionally, the popular orchestras interpreted "the new rhythm", and thusly we had the Pablo Beltrán Ruiz Ochestra recording a song called "Mexican Rock and Roll" and others that sounded more like jive than rock and roll, like Mario Patrón and its Group, comic groups as The Xochimilcas and dances interpreted by Agustín Lara, Luis Aguilar, Eulalio "Piporro" González and Pedro Vargas in the movie Los Chiflados del Rock and Roll.    As it says on the back cover of the first Los Locos del Ritmo LP: "In Mexico, although there was good intention of interesting the public and the Mexican youth in the performances of Mexican artists, a group or performer specializing in rock was never really cultivated. Today, after some years of effervescent victory of rock in United States, Dimsa Records presents practically the first group of specialists in Rock and Roll in Mexico, formed by five young experts of today's more resonant successes and followers of the North American scene. With five voices, two electric guitars and a very uncommon rhythmic style, they are the firmest ramparts in Los Locos del Ritmo, the first authentic rock and roll group in Mexico."   Mexican Rock and Roll from Pablo Beltrán Ruiz, the first record using this words   Cover from the first LP from Los Locos del Ritmo Los Locos del Ritmo recorded 12 songs for their first album, of which six were original compositions, another was a cover of "La Cucaracha," and five were arrangements of North American songs. On their second LP in 1961, there were six originals and six adaptations. In 1962 the third album, based on the twist, the new "rhythm in fashion," came out. Recorded in Venezuela, it included a foreign song, "La Cucaracha Twist," and "La Bamba Twist," as well as "Voy a Buscarte," their own composition. In 1963, their fourth recording had 11 covers and just one original song. From there they became mostly a covers group, like all the other rock and roll groups in Mexico. One of the causes was the death of their singer, Antonio de la Villa, at just 21 years of age. His voice made "Tus Ojos," a Rafael Acosta composition, and "Yo No Soy Un Rebelde" (written by Jesús González) classics of the first era of Mexican rock and of a good part of the 20th century up to the dawn of the new millennium.
