My take, for whatever it's worth, was slightly different, but I by and large agree with most of this post, but here are my exceptions:
The 1st set was pedestrian (there might be a good reason why some songs aren't in the rotation) up until Page's solo in Maze. THEN, the crowd actually got into it after the boys started feeding off of him. Where we were (pavilion, center, towards the rear), half the people weren't even paying too much attention to the music until Page exploded. Then wow.
Seemed like we were just getting into the groove when intermission came.
I need to hear the Hood again, but to me the guitar solo sounded strained. A great Hood (4/4/98, for one) builds like a musical orgasm. Didn't feel any of that with this Hood. Could be me, could be the sound where I was, dunno. I reserve the right to change that opinion after listening again.
Architect? Yawn. Cool lyrics, but didn't nothing else for me.
Mike's Groove? Superb! After that Mike's I was scared that they'd drop into a Hydrogen that would slam the brakes on the momentum that they'd built (they did that a bit later with Waste, but they way it built up into GTBT made it not a bad placement), so the extended Simple was great.

Best thing? No Possum!

Hopefully, tonight will be even better. After that second set, though, the bar is set pretty high.
