Shortly afer, he started rapping in the year 2002, with his song "16's With Me" being the first to hit it big locally. It was produced by South San Francisco producer Big D and sampled the Imperial March from Star Wars. Ya Boy gained more attention from his song "100 Bars of Crack" where he raps 100 bars over Dr. Dre's "Nuthin' But a "G" Thang" beat (featured on The Black Wall Street Journal Vol. 1) and "100 More Bars" which is done in the same style, but it uses the instrumental from the Jim Jones song "We Fly High".Ya Boy was given his name by his cousin Bailey, and was helped to develop into a rap artist by his other cousin San Quinn. In the Summer of 2005, Ya Boy released his first solo mixtape, Future of The Franchise. This was to be followed up by his debut album, Rookie of the Year[3] on Done Deal Entertainment, LLC. His album features E-40, Turf Talk, Clyde Carson of The Team, San Quinn and more. The first single off the album was produced by Rick Rock and is titled "Step Ya Game Up." Done Deal also owns the rights to another Ya Boy album, titled West Coast Machine (originally called The Machine), however, a release date for this album has not yet been determined. All songs on the album were recorded from 2004-2006 while Ya Boy was still Done Deal's number one rapper. It is a big possibiblity that the album will not ever be released.
