Mexican rock music, often referred to in Mexico as rock nacional ("national rock"), originated in the 1950s with covers of standards by Chuck Berry, Elvis Presley and The Everly Brothers, among others, bands such as Los Rebeldes del Rock, Los Locos del Ritmo, Los Crazy Boys, Los Nómadas, and Javier Bátiz soon arose with original compositions, often in English. The group "Los Nómadas" was one of the first racially-integrated bands of the 1950s. Their lead guitarist Bill Aken (Adopted son of Mexican movie actress Lupe Mayorga, said adoption making Aken the cousin to Ritchie Valens) wrote most of their original material, including the raucous "Donde-Donde," and co-wrote the material for their "Sounds Of The Barrio" album that is still being sold by various Internet web sites. Their 1954 recording of 'She's My Babe' was the first top 40 'R & B' recording by a Latino band. In the southwest U.S. Spanish guitar rhythms and Mexican musical influences may have inspired some of the music of American musicians Ritchie Valens, Danny Flores (of The Champs), Sam the Sham, Roy Orbison and later, Herb Alpert. Initially, the public exhibited little interest in them, because of media attention paid to La Ola Inglesa (British Invasion).

Carlos Coy (born October 5, 1970), better known by his stage name South Park Mexican, is an American rapper, founder of Dope House Records, and convicted felon. His stage name is derived from the South Park neighborhood in Houston, Texas where he was raised.

Coy's sister, Sylvia, described herself as his "mother-sister". Coy attended various elementary schools, before entering the music magnet program at Welch Middle School. His family moved from southeast Houston to South Park, and Coy attended Woodson Middle School. Rapper Scarface (real name Brad Jordan) also attended Woodson. Coy attended Milby High School until he dropped out in 1987 while still in ninth grade.
