Jah Wobble is a pseudonym of John Wardle, who was Public Image Ltd.'s bass player, from 1978-80. He left PiL on shaky terms, after using the band's backing tapes (from "Metal Box" / "Second Edition" recording), for his first 'solo' release, "Betrayal" (1980).
Afterwards, he made a number of independent releases, first with the The Human Condition (featuring ex-PiL drummer Jim Walker). Soon after, he collaborated with Jaki Liebezeit and Holger Czukay (of Can), plus David Howell Evans (aka The Edge, of U2), resulting in "Snake Charmer" (Oct 1983, Island Records). At the same time he released his own solo work. Further releases were supported by Island Records.
