Def Leppard was formed in 1977 in Sheffield, South Yorkshire, England. The band forged an accessible melodic version of heavy metal that was slower to catch on at home than in the United States, where a new British Invasion of pop-oriented heavy metal bands revived the fading genre. Def Leppard went on to become one of the most popular rock groups of all time with hits that include "Pour Some Sugar On Me", "Armageddon It", "Animal" and "Rock Of Ages."
