Your first metal show

Dragonforce with All That Remains and HORSE the Band. HORSE and All That Remains sucked. Dragonforce, whatever you may say about their studio work/name/image/whatever, are an unbelievable live band. Who else shreds while jumping on trampolines?
Second show was Iron Maiden with Bullet for my Emo supporting.
 
Motorhead with Anthrax, Skew Siskin and Psycho Squad back in November 2002.

Skew Siskin and Psycho Squad sucked but Anthrax were awesome and Motorhead just destroyed the place.
