"Metal Box is the second album by Public Image Ltd., released in 1979 by Virgin Records.
The title refers to the album's original packaging, which consists of a metal 16mm film canister embossed with the band's logo and containing three 12" records. The album was reissued in 1980 as a double album titled Second Edition.
A radical departure from Pil's relatively conventional debut, the avant garde, abstract Metal Box was characterized by singer John Lydon's cryptic vocals, Jah Wobble's propulsive dub reggae-inspired basslines, and a unique, "metallic" guitar sound (guitarist Keith Levene played Travis Bean guitars which have aluminum necks). Metal Box is widely regarded as a landmark of post punk and experimental rock: In 2002, Pitchfork Media ranked Metal Box at #19 on their "Top 100 Albums of the 1980s,"[1], while In 2003, the album was ranked number 469 on Rolling Stone magazine's list of the 500 greatest albums of all time."
