One of the best shows I have ever seen was Anthrax, MEGADETH, and Slayer. I went to see the machine that is MEGADETH. Anthrax totally stole the show. They came out and were so high energy.
I saw this show in Lakeland Florida July 13th 1991. This is the same show where Slayer recorded one of the two discs on their Decade of Aggression live album. That show was friggin crazy. My friends and I traveled from south Florida to go to the show. The closer you got to the show, the more people there were on the highway hanging out of windows and screaming "Slayer, SLAYER". But I have to agree. Great show, and for me, Anthrax layed it down. Think Slayer played first, then Anthrax, and the show closed with Megadeath. All in all, it is a crappy place to play acoustically speaking. It is a big metal box, and the bands just kept getting louder and louder. By the time Megadeath got on stage, it took me half the song to be able to hear what song they were playing.
I missed the show here in Seattle Easter weekend because I was in Florida for my brother's wedding.
Glad someone had a good time though.
