He was born in Princeton, Texas and was a fixture in the Dallas music scene throughout the 1990s playing in well-known clubs. In 1999, he formed Drowning Pool. The band released the album Sinner in 2001. Williams was often known for his positive, friendly attitude.

He died on the band's tour bus in Manassas, Virginia. At the time of his death there was much speculation about the cause; this was laid to rest by a coroner's toxicology report which showed that Williams suffered from undiagnosed cardiomyopathy, a form of heart disease.
