Public Image Ltd (PiL) are an English post-punk band formed by vocalist John Lydon, guitarist Keith Levene and bassist Jah Wobble, with frequent subsequent personnel changes. Lydon is the sole constant member of the band.
Lydon emerged after the break-up of the Sex Pistols with PiL's First Issue (1978). His new band had a more experimental sound: Wobble's "droning, slow-tempo, bass-heavy noise rock, overlaid by Lydon's distinctive, vituperative rant." Their early work is often regarded as some of the most challenging and innovative music of the post-punk era. Their 1979 album Metal Box was ranked number 469 on Rolling Stone magazine's 2003 list of the 500 greatest albums of all time. The NME described PiL as "arguably the first post-rock group".
