I'd have to say KISS on the 'Revenge' CLUB tour in April 1992, a 13-city jaunt that was essentially a live "listening party" for their new album at the time. They previewed the entire 'Revenge' album during intermission prior to the show and then pummeled 1000 people with a 22 song set. They truly let the music do the talking and took no prisoners that night. In short order, they've NEVER sounded better live since OR after. With ANY lineup. Good times (
)!
