His mother sent him to study sculpture, painting and ceramics at the art academy in Oaxaca. It was there that he heard the sounds of classical music and learned to play cello on a borrowed instrument. He then switched to a guitar which was a gift from his brother, because his family could not afford a cello. At the Benito Juarez Autonomous University in Oaxaca, Gutiérrez studied classical guitar and his musical interests spread to diverse genres including classical, flamenco, son cubano and jazz.
At age fourteen he began playing classical guitar in restaurants in Oaxaca and caught the attention of German born guitarist Wolfgang “Lobo” Fink of Willie & Lobo. At 17, he teamed up with Fink to play venues in San Miguel de Allende, Mexico. When Fink returned to Germany, Gutiérrez went to Mexico City to study jazz earning money by playing his guitar on city buses. The guitarist has played in South America and Spain with Ana Gabriel, Ricardo Arjona, Francisco Cespedes, and Pedro Guerra. A virtuoso with the nylon string guitar and tres, Gutiérrez has performed at the Kennedy Center, the Mexican Cultural Institute of the Mexican Embassy in Washington D.C. and to a crowd of 10,000 people at Millennium Park, Chicago. Gutierrez is recognized for his unique ability to connect with the audience  and channeling a bit of the local energy into each performance.
Gutiérrez talent was then discovered by Doc Severinsen who heard him play in a restaurant in San Miguel de Allende. Severinsen led the NBC Orchestra for twenty years on Johnny Carson's Tonight Show. They recorded their first album together in 2007 called En Mi Corazon. Gutierrez is the band leader, founder and musical director of the group the San Miguel 5  and they have performed with symphony orchestras across the United States. Other musicians of the San Miguel 5 include Grammy award winning violinist Charlie Bisharat, Cuban percussionist Jimmy Branly and bass player Kevin Thomas. In 2011 Gil Gutiérrez and Doc Severinsen played at New York City's Carnegie Hall accompanied by the New York Pops under the direction of conductor Steven Reineke.
Gutiérrez has performed as a soloist with the Minnesota Symphony, Florida Symphony and with the Doc Severinsen Big Band Tour in Dallas, Texas. In 2013 he was the featured artist and directed the ensemble at the Calaca Festival honoring Chavela Vargas in San Miguel de Allende. Constantly pushing boundaries as a musical director he brings together new combinations of musicians and musical styles. These include opera, jazz, cantaor flamenco, Cuban and Mexican styles to create performances considered the cultural vanguard. Among his works are performances of his original compositions with the New York Choral Society and scoring of several films including El Cochero, El Alcazar de Chapultepec and Una Causa Noble. Gutiérrez composed and performed the soundtrack for the documentary film Lost and Found in Mexico. In 2013 Gutierrez was featured in the National Geographic Traveler documentary The Granny Diaries. He was a special guest soloist with Arturo Sandoval in the Mexico City Palace of Fine Arts.
He continues to tour and perform in Canada, Latin America and the United States.
