Mexican Rock 'N Roll band formed in Mexico City in 1959. One of the front-runners of the first wave of Rock sung in Spanish where the translation to Spanish of current rock 'n roll songs was the norm.

Their first single (a 78 rpm) was released in May 1960, which included the songs La plaga (spanish adaptation of Little Richard's Good Golly Miss Molly) & El rock de la cárcel (spanish adaptation of Elvis Presley's Jailhouse Rock).
