Def Leppard have been talking for years about putting together an expanded reissue of their 1996 'Slang' album, but it wasn't just idle chatter: On Feb. 11, the band will bring the record back to stores with an added disc of demos and unreleased tracks.

Recorded in the wake of the group's stratospheric success with its 'Pyromania' (1984), 'Hysteria' (1987) and 'Adrenalize' (1992) albums, 'Slang' found Def Leppard taking a surprising turn away from their trademark heavily layered sound and adapting a more organic approach, with exotic-sounding instruments like the sarangi and dhol scattered among the usual guitars, keyboards, drums and bass. While it was certainly an admirable departure in theory -- and the band would probably have been criticized if it had tried to copy those earlier records anyway -- 'Slang' was a marked commercial comedown, selling less than a million copies and breaking the group's string of multi-platinum efforts.

While the record was widely dismissed as a misguided attempt to chase changing trends at rock radio, 'Slang' was just as influenced by the absence of producer Mutt Lange, who'd helmed the band's previous records and pushed them toward recording more uptempo, arena-ready anthems. With Pete Woodroffe co-producing alongside the band, Def Leppard were free to indulge their more introspective impulses, and although the sessions didn't produce anything as radio-friendly as 'Pour Some Sugar on Me,' the album did spin off a handful of European hits, with the second single, 'Work It Out,' breaking the Top 10 of Billboard's U.S. Mainstream Rock Tracks chart.

The expanded 'Slang,' which will be available in CD, digital, and vinyl formats, tacks on 19 additional tracks, many of which have never been officially released. The album is already available for pre-order via online music retailers.
