Def Leppard Releases Deluxe Editions

The group has decided to release two of their most popular albums in deluxe versions.

The English band, who was very successful in the 1980s and 1990s, will release re-mastered versions of Pyromania and Adrenalize for their fans, Billboard.com has learned.

Each of the albums includes a second CD of previously unreleased demos and songs that were recorded live during concerts at their height of popularity.

The pop metal group, formed in 1977, will begin a new tour this summer with Poison and Cheap Trick. The tour, which includes 40 shows, will begin on June 23 in Camden, New Jersey.
