Whose multi million selling LP is titled "Pyromania"?

Whose multi-million-selling LP is titled "Pyromania"? The answer is Def Leppard.

Released on January 20, 1983, Pyromania is the English rock band’s third studio album. Produced by Robert John “Mutt” Lange, it helped transform Def Leppard from a rising British heavy-metal group into international stars. The album blended hard-rock guitar work with polished, highly layered production that appealed to both rock audiences and mainstream radio.

Pyromania produced major songs including “Photograph,” “Rock! Rock! (Till You Drop),” and “Foolin’.” “Photograph” became one of the band’s signature tracks, while the album reached No. 2 on the Billboard 200 in the United States. It was also a major step toward the even larger success of Def Leppard’s next album, Hysteria.

A common mix-up is confusing Pyromania with Hysteria, the band’s 1987 follow-up. Both albums became enormous sellers, but Pyromania came first and sold more than 10 million copies in the United States, earning Diamond certification from the RIAA.
