Def Leppard juiced up the lumbering blooze riffs of Led Zeppelin, put a spit-shine sheen on 'em, and slapped five thousand vocal tracks on the chorus. The result: humongous metal anthems with tongue-flickering axemanship and arenas full of topless teenage girls. Steadfastly working through a number of personal tragedies, the band has managed to keep releasing records right up till 1999 and, maintaining a huge cult fan-base, shows no sign of quitting.
