Diego San Martino Jazz Singer

Diego is amazing! He is a new American idol! - Michael Bublé, (AT&T Center, March 27, 2019)

Diego is 19 years old and has been singing in front of crowds for a number of years, despite his young age, with his involvement in musical theatre around the city of San Antonio. After a hiatus from the stage he never lost his love of singing. He caught the bug to sing jazz after hearing the music of Michael Bublé and Frank Sinatra. After discovering the soul of this music, he made it his goal to sing with a big band jazz orchestra one day. The opportunity came in 2018 when he was invited to listen to a local big band, the Beethoven Big Band, and then invited to sing a song with them. He was immediately asked to join the band as their male vocalist and he hasn't looked back since! He has sung at Fiesta San Antonio events, outdoor shows at the Beethoven Beer Garden, and private parties with the big band. He is presently promoting his music by performing one man shows around town as Diego San Martino - as a nod to his Italian heroes Frank Sinatra and Dean Martin. He has grown in his repertoire and development as a singer and wishes to continue entertaining crowds wherever he has the opportunity.
