About Us

John Vargas and David Vargas (aka "D-Varg")

Fremont natives John Vargas and David Vargas (aka “D-Varg”) joined forces to write original songs that combine contemporary jazz, bossa nova, hip-hop and R&B genres. While our first love is composing songs – we produce and perform our music with our band 510JAZZ.

Our original songs are inspired by the great works of master composers Antonio Carlos Jobim, Ivan Lins and Celso Fonseca.  Our arrangements are inspired by legendary producers Quincy Jones and Sergio Mendes.

We strive to bring talented musicians from the Bay Area to our Fremont studio, to produce new original hits. John Vargas is a vocalist (as well as bandleader and executive producer). D-Varg is an accomplished rapper who infuses new flavor into our sound (and also produces and engineers our music).

Our debut album Bossa510 launched in December 2015.

On February 12, 2018, we launched our second album January 16.
