Billy Cox is a bassist, best known for playing with guitarist Jimi Hendrix. He was born in West Virginia. Billy first met Hendrix in the early part of the 1960s, when they were both in the United States Army, stationed at Fort Campbell. Cox teamed with Hendrix in an R&B band called the King Kasuals. The two performed at clubs in Nashville, Tennessee. While in England, Hendrix invited Cox to join him in a new band; Cox declined, preferring to work in various backing bands. Wikipedia
