Public Image Ltd (abbreviated as PiL) are an English post-punk band formed by singer John Lydon (a.k.a. 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.
Following his departure from the Sex Pistols in January 1978, Lydon was eager to pursue a more experimental project and formed PiL. Later that year, the group released its debut First Issue (1978), featuring an abrasive, bass-heavy sound and drawing on elements of dub, noise, and progressive rock. Their second album Metal Box (1979) pushed their sound further into the avant-garde, and is often regarded as one of the most important albums of the post-punk era.
By 1984, both Levene and Wobble had departed, and the group came under the direction of Lydon. Subsequent albums included This Is What You Want... This Is What You Get (1984). After a late 1990s hiatus, Lydon reformed the group in 2009 and has released several further albums, most recently What the World Needs Now... (2015).
