I'm diggen how the crowd is allowed up to the stage like the old club days. Those two girls in front of James headbanging during Fight Fire with Fire is pure awesomeness...
They need to play that song again during the 72 Season tour. Possibly next year, when it will be the 40th anniversary of the Ride the Lightning album (Implying they'll have to also play Trapped Under Ice and AGAIN, the song Escape they never want to play again!)
Their 5 first album are close to perfection anyway. I couldn't imagine becoming a die hard metalhead without listening them back and forth when I was a teenager in 90's... They are the fundamental, a link between the old school of the 70's and early 80's where they took all their inspiration, and the modern stuff that rose in the 90's and afterwards...
