On this day in 1979 Public Image Ltd. (PiL) released their second album Second Edition. The album was originally released as Metal Box, taking it’s name from the metal canister that contained pressings of the record. A standard version was later released as Second Edition which featured the same tracklist. On this album lead singer John Lydon pushed his ambition to shed the restrictions of Punk Rock, which became too commercialized and one-dimensional even further by incorporating elements of Dub, Post-Punk, and Krautrock, all of which were no-go territory for Punk Rock purists. This was the last album to feature original bassist Jah Wobble, and though the band still thrived following his departure, Wobble’s input is irreplaceable on this album with his Dub/Funk inspired bass grooves which complimented Keith Levene’s wall of disjointed guitar sounds and John Lydon’s wailing vocals perfectly. Second Edition is an essential album in the Post-Punk world. Happy Anniversary.
