It was truly awesome, my back felt nearly broken afterwards and I almost couldn't walk at all XD. It was hard to see the members at times, but I still saw them, and they basically performed perfectly. Except for a couple of things, the fact that they've still got 'the last live' guitar solo for kurenai playing instead of sugizo doing it was very meh, they should've sorted that out by now. And Toshi was brilliant, and there was only a couple of times in the concert where his voice went weak/cracked up, at some points I thought his voice was too high like he'd sucked in helium, but after seeing some videos on youtube it seems Toshi's voice sounded normal, I think it was the acoustics of the theatre and the bass might've been distorting how I heard his voice.
But yeah the concert was amazing (Except Drain, its just...drain) Sugizo's violin solos were epic and Yoshiki wasn't just doing the usual 'uuuuup, doooown SLAM SLAM SLAM' routine with the piano he was adding a lot of original things into it.
I completely expected the crowd to be nuts, it was kind of obvious after the reports of the tour last year. The people getting piggy backs was a bit annoying though. There was one guy (I'm sorry if it was anyone on here) who i think went ott with what he was shouting to the band, infact two people were shouting "shut up and get on with it!!" "less talking, more singing!!" while the band were on stage when everything was silent. I think the band will definatly come back to London based on most of the crowd reaction, but what those guys were saying isn't going to help is it. I havn't heard anyone else at any other X concerts shout that.
And yeah, the thunder was utter insanity.
