This two-fer from Universal includes Def Leppard's massively successful 1987 album Hysteria and its disappointing 1992 follow-up Adrenalize -- the former, paired with 1983's equally stellar Pyromania, would have made a more attractive package. Longtime fans will already have Hysteria, and unless they have a strong stomach for paint-by-numbers ballads, will have little use for Adrenalize. ~ James Christopher Monger
