Legendary English rock band Def Leppard brought the circus back to town last week. Paired up with fellow hair-metal survivors Whitesnake, the group began a four-date Japan tour with two nights at the prestigious Nippon Budokan in central Tokyo on Oct. 23 and 24. The two behemoths of 1980s pop metal have each weathered rather differently with age, and it showed on the opening night. While Whitesnake dragged themselves around the stage and lumbered through an uninspiring set, Def Leppard, buoyed by their latest album hitting the Top 10 on both sides of the Atlantic, captivated the audience as if time hadn’t passed at all.
