First-rate melodic pop-metal. Def Leppard tracks like "Let's Go,"..."All Time High" and "Broke 'n' Brokenhearted" exude the band's classic mix of Seventies pomp-glam riffing, Eighties electro-shock rhythms and patented, tremendously stacked chorus vocal harmonies in a manner that's strikingly redolent of their past. But the album also finds the band moving beyond well-trod territory, as evidenced by the slinky pop-funk strut of "Man Enough," the downtuned, acoustic psych-blues of "Battle of My Own" and the sleek New Wave isms of "Invincible." - Rolling Stone
