Def Leppard is the 11th studio album by British rock band Def Leppard. It’s the band’s first release since Songs From The Sparkle Lounge (2008), marking the longest gap between studio albums in their career. The 14-track album not only nods to their history, but it hints at their future. According to vocalist Joe Elliott, “The name itself sums everything up. It’s a misspelled nonsensical mad-looking two words.” This is Def Leppard in 2015. This is rock ‘n’ roll. Let’s go.
