Los Baby's are a rock band from Yucatán, Mexico. Their native town of Tizimín is close to Mérida, the state capital.
The group began performing together in 1958, at which time it was composed of the four Avila Aranda brothers. They debuted at the Fantasio theater in Mérida in 1960, then performed in Belize, where they took the name Los Baby's del Rock. They recorded their first sides for Discos Orfeón in 1959, but the label did not release them until 1962 once rock & roll began to become popular in Mexico. They toured throughout Mexico in the middle of the decade, and around this time they also made numerous appearances in television advertisements. In 1964, they made their first recordings for Discos Peerless, often covering the hits of foreign groups to great success. They became one of the most popular native pop acts in Mexico in the 1960s.
In 1986, the compilation 16 Exitos (16 Hits) charted in the United States, reaching #15 on the Billboard Regional Mexican chart.
Emilio and Armando died in the early 90s, but Carlos and Enrique still tour with Carlos Jr. on drums and guest keyboard and bass players.
