Just got back from last night.
Incredible show as expected. Sound quality was my biggest worry going into it but it was perfect from where I was (mezzanine). YMMR was one of the most, if not the most intense live music experiences I ever had. Chest-rattlingly awesome.
And it went by really quick; definitely felt a lot shorter than it actually was. So yeah, the whole losing track of time thing is true.
I think they did cut a couple songs from the usual set they've been playing, though. Blown a Wish and Sueisfine. Wonder why that was. Also, I would've rather heard Lose My Breath instead of Cigarette in Your Bed but that's just being picky.
Oh and one reason why one would rather see them now as opposed to in the early 90's is that the ability for them to reproduce live what they did in studio is available to them now. Go back and listen to any older recordings; they all don't come close. The recordings I've heard and the show I saw last night matched everything on the albums note for note and with perfect clarity.
