On April 26th, for the 40th anniversary of the release, Def Leppard will reissue Pyromania as a Super Deluxe Edition Box Set. The 4 CD package with Blu-ray, will contain unheard demos, rough mixes, and live shows from that era, with performances from Germany and Los Angeles.

Originally released in 1983, the album sold more than ten million copies and earned a prestigious Diamond Award early in their careers.

Pyromania produced global hits such as “Photograph” “Rock Rock (Till You Drop),” and “Rock of Ages.”
