"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.
