Originally issued in 2011, Mirror Ball served as Def Leppard's first ever live album, recorded across the world over the course of many of the band's sold-out dates on The Sparkle Lounge Tour 2008-2009. The album captures the group's legendary concert experience at its thunderous best, bringing together live versions of classic Leppard hits like "Photograph," "Pour Some Sugar on Me," "Animal" and "Rock of Ages." With their creative juices at full flow, the band also added three new studio tracks: "Undefeated," It's All About Believin'" and "Kings Of The World," that are undeniably Def Leppard and take their place with ease within this classic setlist.
