Powered by stadium-filling drums, rapturous guitars, and unshakable choruses, the record saw DEF LEPPARD rightfully claim their place among rock's divinities forever. As a result, its influence now reverberates through three generations of artists to follow. It also historically marked their third straight collaboration with producer Robert John "Mutt" Lange.
