My favourite concert moment was back in january 24 of 2004 in toronto. After PoD finished, the meteora themed Linkin park curtain was up in front of the stage. The crowd waited for Linkin Park. As soon as the lights went out, the crowd cheered in excitement. You could hear Session on the speakers, and when the curtain dropped, the band started to play With You. It was an all at once moment with the guitar, bass and drums kicking in. But the real adrenaline rush kicker was Chester screaming as loud as he could for the 11 second or so intro scream to the song that they have done live with it since Reanimation.
Linkin park has many memorable moments, but this was one of my favourite.
