Recorded last year during month-long stints at lead singer Joe Elliott's Dublin studio, the album's title refers to a backstage area called "The Sparkle Lounge" on Def Leppard's 2006 tour where the band would go to write songs. In addition to the album's hit single "Nine Lives," other standout tracks on the album include "C'mon C'mon," which will be the album's next single, "Go," reminiscent of the band's classic track "Rocket" in its power and aggressive tribal beat; "Love," an emotive and moving epic song; and the anthemic "Tomorrow," a song written by guitarist Collen about the death of his father.
