Vallenato musical group formed in 1983 by accordionist and vocalist Omar Geles Miguel Morales. Its name comes from the nickname he received from Omar Geles child who eventually became the sole director of the organization, the name became known after 1986, because in the beginning was conceived under the name Omar Geles "el diablitol" and Miguel Morales.
