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.
