"Amazing" wouldn't do it justice.
Seriously though, performance overall was really good. The final setlist was an impressive and varied selection (with even songs from Belmont's Revenge (!)), having a quite varied range of styles either focused on orchestra, rock band, both combined or solos like piano, singers and organ. It was also evenly distributed and had a really good flow through the concert; p.e. I loved the ending with Dance of Illusions and the Ending fom CV4.
Michiru Yamane performed a couple of times, playing the hapsichord on Wood Carving Partita and Wandering Ghosts on the encore, and the piano on Dance of Pearls.
My favorites were the old school medley (the Beginning part is so bombastic and grand it makes me shiver), the GB piano solos (these were incredibly creative and awesome), Chandeliers (the orchestral arrangement worked extremely well) and Dracula's Castle. Though, really, the whole concert was spot on. There's a couple of videos on youtube, so go check them out to get an idea of how it was.
I really really hope they release a CD an/or DVD so people both attendants and non-attendants can relive the experiencie. It would be such a waste of so good material.

In conclusion, it was an epic night I'll hardly ever forget :_).

Did someone else go? I met The Gambler from VGMdb, but didn't came across any people from here.

(here's some of the YouTube vids)

Liked some parts of the Ripe Seeds/Psycho Warrior segment, starting around 4:00 min mark, then gets cool again at 5:30 onward

Theme of Simon obviously benefits from the hall's organ.

(Although I'm not quite sold on the Rock & Orchestra combo being the optimal mix for this, as their arrangement seems to heavily depend on the rock side.)

Oooh, Dance of Pales is lovely as expected.

It's difficult to judge the quality of the arrangements and performances by these videos - so I won't.

It was mentioned in this interview that there wouldn't be any official recording done, due to it likely not being worth it financially.

It's also hinted that they have another (still secret) project in the works, and that whether it will become a reality or not partly depends on the outcome of this concert.

Thanks for the Youtube links, guys!

Herrkotowski, you say Kinuyo Yamashita composed the Megaman X3 soundtrack, but I have Toshihiko Horiyama, Syusaku Uchiyama, Yoshino Aoki, and Makoto Tomozawa listed for it, based on information I got from the X-X6 box set. Did they only do the Saturn/PSX remixes?

I tried to watch them, and, I have to say - they should be removed from the internet. With quality that horrible, it would be better to have nothing.

Hell, we'd have to delete 80% of the whole 'net then.

I suspect Jodo wouldn't find a fault with that.

Interesting interview with Michiru Yamane  (before Castlevania - The Concert).
