Def Leppard is an English rock band formed in Sheffield, South Yorkshire in 1977, and one of the best-selling music acts of all time with over 100 million records sold worldwide. The band coalesced around vocalist Joe Elliott, guitarists Pete Willis and Steve Clark, bassist Rick Savage, and drummer Rick Allen, later adding guitarist Phil Collen as a permanent member in 1982. Emerging from the New Wave of British Heavy Metal movement that also produced Iron Maiden and Judas Priest, Def Leppard quickly distinguished themselves from their peers by pursuing a more melodic, polished, and commercially accessible sound that would eventually make them one of the dominant rock acts of the 1980s.
The band's early albums On Through the Night (1980) and High 'n' Dry (1981) established their hard rock credentials and brought them to the attention of American audiences through heavy MTV rotation, but it was their collaboration with producer Robert John 'Mutt' Lange on Pyromania (1983) that truly launched them into the stratosphere. Pyromania spent 92 weeks on the Billboard 200, reached number two, and sold over ten million copies in the United States alone, producing arena rock anthems including Photograph, Rock of Ages, and Foolin' that defined the sound of early MTV-era rock. The album's meticulous multi-layered production — with Lange coaxing extraordinary vocal harmonies and guitar textures from the band — set a new standard for hard rock record-making that influenced countless acts that followed.
The making of their follow-up album Hysteria (1987) became one of the most dramatic stories in rock history. In December 1984, drummer Rick Allen lost his left arm in a car accident near Sheffield, a catastrophe that would have ended most careers. Allen refused to quit, working with engineers to develop a custom electronic drum kit he could operate with his feet, and returned to the band after an extraordinary period of rehabilitation and adaptation. Hysteria itself took three years to complete and cost over four million dollars to record, leading many in the industry to predict commercial failure. Instead it became one of the best-selling albums of all time — spending 49 weeks at number one in the United Kingdom and reaching number one in the United States, producing seven singles including Pour Some Sugar on Me, Love Bites, and Animal, an almost unheard-of achievement for a single album.
The band suffered another devastating blow in January 1991 when guitarist Steve Clark was found dead at his London home following a toxic combination of alcohol and prescription drugs, a loss that cast a long shadow over the recording of their next album Adrenalize (1992). Guitarist Vivian Campbell joined as Clark's replacement and has remained a member ever since. Despite the tragedies that marked their peak years, Def Leppard have continued recording and touring with remarkable resilience, releasing a string of albums and maintaining one of the most loyal and enthusiastic fanbases in rock. They were inducted into the Rock and Roll Hall of Fame in 2019, a recognition their record sales and cultural impact had long warranted, and continue to sell out arenas around the world on the strength of a catalog that defined a generation of rock and roll.
