This band was responsible for a movement in musical influence from North to South rather than the other way around, as is more usual in Latin music. The brothers Ayala formed the band with accordion and keyboard player Rudy Flores in California in 1972. The membership spread between the towns of Modesto and Turlock. Jose Luis Ayala, Johnny Ayala, and Alfonso Ayala put all the possible bonded energies of brotherhood into their band and in collaboration with Flores, a fine musician, the band went on to score a series of hits between 1972 and 1988, when the original version of the band broke up. "Ambition," or "Ambicon," was the prophetic title of the band's first hit on the Tejano scene, a record that also marked the first international smash for the Discos Fanas label as well. The band put out dozens of records on labels such as Phonovisa, RCA, and Thump. In the meantime, what was perceived as the band's original style spread back to musicians in the Nueva Leon area of Mexico, where it was adopted as the "Monterey style."
