Public Image Ltd (also known as PiL) are an English post-punk band formed by singer John Lydon (aka Johnny Rotten), guitarist Keith Levene, bassist Jah Wobble, and drummer Jim Walker. The group's personnel has changed frequently over the years; Lydon has been the sole constant member.
Lydon emerged after the break-up of the Sex Pistols with PiL's Public Image: First Issue (1978). The new band had a more experimental sound than the Pistols: a "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".
