Def Leppard's next studio album, Pyromania, was released in January 1983, with ' Photograph' and ' Rock of Ages' both topping the US Rock Tracks chart and reaching the top 20 of the Hot 100. Their second album, 1981's High 'n' Dry, was produced by Mutt Lange, who helped them begin to define their melodic hard rock style, and the album's most popular track ' Bringin' On the Heartbreak' became one of the first rock videos played on MTV in 1982, but the album only reached the Top 30 and 40 in the UK and US.

Their first album, 1980's On Through the Night, reached the Top 15 in the UK but received little notice elsewhere. The band's greatest commercial success came between the early 1980s and the early 1990s. They established themselves as part of the new wave of British heavy metal movement of the early 1980s. Since 1992, the band has consisted of Rick Savage (bass, backing vocals), Joe Elliott (lead vocals), Rick Allen (drums), Phil Collen (guitar, backing vocals), and Vivian Campbell (guitar, backing vocals).

Def Leppard are an English rock band formed in 1976 in Sheffield.
