Gari got his start in music playing guitar in a rock band, doing gigs in pubs and nightclubs until the lead singer left and Gari was called on to fill the spot. It was then that he decided to begin formal vocal training in order to build the endurance needed to be a lead singer. His teacher recognised Gari's strong, natural spinto tenor voice and encouraged him to train for classical and opera. Gari formally studied in guitar and piano and he has worked with prominent vocal coach Fernando Bandera in Italy. He has also worked with many music coaches from the Guildhall School of Music and the Trinity School of Music. His first opera role was as Cavaradossi in Puccini's "Tosca". Since then, he has performed leading tenor roles in operas such as "Carmen", "La Traviata", "La Boheme", "Pagliacci", "Cavalleria Rusticana", and "Aida". Gari has also built an impressive repertoire in operettas, especially in Gilbert & Sullivan. His roles have included leads in "The Pirates of Penzance", "The Merry Widow", "The Mikado", "HMS Pinafore", "The Gondoliers", "Ruddigore", as well as on the musical stage in the role of Tony in "West Side Story". He has sung for Prince Albert of Monaco and HRH Sophie the Countess of Wessex, and has performed on concert stages in England, Italy, Scotland, Wales, Ireland, Spain and Canada.
Gari has performed in venues such as the Royal Albert Hall, the Studio Theatre in the Royal Opera House Covent Garden, the Port Theatre (Vancouver), Hever Castle, the Royal Courts of Justice, the Natural History Museum, the Dali Museum, Squeryes Court, Chartwell, Groombridge Place, and Chatsworth House. In 2008, Gari performed his first solo concert at the indig02 in London to a sold-out audience, which was met with rave reviews. In 2009, Gari released his debut album "Serenata", a collection of Italian love songs including two songs which were penned by renowned composer Andrea Bellentani and Cristina Pavarotti, daughter of the famed opera tenor Luciano Pavarotti, and which were among several songs offered personally to Gari by both Bellentani and Pavarotti. Gari followed up "Serenata" with his second album "Somewhere" in 2011, which includes three completely original songs. In 2012, he released his third album "Come What May", his first all-English album of songs from the musical theatre and classical/crossover genres. "Full Circle", a collection of favorite arias and Neapolitan songs, was released in 2014. Gari's latest album, and his first in the gospel genre, "It Is Well With My Soul" was just released in December of 2016.
Being a versatile singer, equally at home in music ranging from rock and musical theatre to classical and opera, has earned Gari many fans from around the world.
