Born in Guadalajara, Mexico, and raised in Fresno, California, Gilbert’s musical career was preordained; the only son to his eponym father, a touring Cumbia band leader, singer and arranger, Gilbert was strongly influenced by his predecessor’s deep appreciation for classical composers and big band jazz ensembles, broadening young Gilbert's horizons from an early age. Gilbert Sr. strongly encouraged Gilbert toward the Jazz genre when at first he showed an interest in trumpet at age 6. By age 11, Gilbert’s intensive training and education provided the context to begin playing professionally, and at age 15 he preformed with mentor and icon Dizzy Gillespie at the Monterrey Jazz Festival.
