They were far from boring the first time I saw them. They were opening for Ozzy after the release of Master of Pupets, one of the craziest shows I've been too. Cliff had a wild solo during Anesthesia...by that point in '86 / '87 they were huge in the NYC tri state area..kill em all and ride the lightning were on the top of the play list at any highschool party, at least any party that mattered. The band came on stage to a heroes welcome and proceeded to bolw the doors off the Brendan Byrne Arena.
At that time,the band had no air play on thd radio and MTV had not been given a video to play until Justice's One.
The other shows I've seen since, 5 maybe 6 shows, never matched that intensity.
