Personal information

Born on: 15.01.1965

Jones was born in Park Ridge, Illinois, raised in Libertyville, Illinois.He was accepted into the Suzuki program, and continued to play violin through his freshman year in high school. He then began to play an acoustic bass for three years in an orchestra.

In addition to playing classical music, Jones played bass guitar in the band Electric Sheep, with Tom Morello of Rage Against the Machine, until Jones moved to California (Morello soon followed). According to both of them, the band was quite unpopular at the time. Jones never received traditional guitar lessons, but instead learned by ear.
