Formed in California in 1972, the Ayala brothers and Rudy Flores created a musical movement that shifted influence from North to South in Latin music. The band, initially known as "Los Humildes," produced hits between 1972 and 1988, impacting the Tejano scene and inspiring the "Monterey style" in Mexico. After the original band split, spin-off groups emerged, continuing to tour and record into the 21st century. Los Humildes de los Hermanos Ayala and los Humildes de Rudy Flores released albums on various labels, with the former being more prolific and paying tribute to Mexican singer Javier Solis on their 2016 release.

Despite the split of the original band in the late '80s, the musicians maintained the name "Los Humildes" through spin-off groups, each offering a unique perspective on their music. The band's influence on the Nueva Leon area of Mexico led to the adoption of the "Monterey style," showcasing the enduring impact of their original sound. With a discography spanning multiple labels and decades, the Ayala brothers and Rudy Flores continue to create music that resonates with fans, with their dedication to their craft evident in their extensive studio albums and live performances.
