Mexican singer and songwriter Sergio Esquivel started getting involved in music while studying physical education in Mexico City, writing lyrics at night inspired by the family he left behind. A ballad dedicated to his sister called "Rocio" became his first song. Back to Yucatán, Sergio Esquivel started working during the day and performing at night. In 1968, Esquivel formed a short-term duet with Ramón Triay. Soon after, the artist returned to Mexico City spending precious time while studying music and planning his solo career. In 1971, Sergio Esquivel came in third place at Mexican First International Popular Song Festival; he later participated in major Latin events such as Viña del Mar and OTI's festivals. ~ Drago Bonacich
