No matter how hard Def Leppard pushed 1999´s Euphoria, it just didn´t take off. No matter how many times they were on VH1 in the years separating that album and its successor, 2002´s X, the group failed to stay in popular consciousness as an active band ? after all, a much-repeated Behind the Music and a made-for-TV biopic aren´t the best way to signal that a band is still vital. X isn´t likely to change that reputation, either, since much of it sounds like the band is desperate for a hit again. To their credit, they´re not chasing the new, hip sound ? no stabs at nu-metal or rap-rock here ? but they´ve decided to act their age.
