If you're interested, this site starts with a short trailer:

It was fantastic! Such overwhelming drum-, flute-, horn- and many others sounds. I read, they've been on tour in the US, last year? For those in Germany, who can watch them, I say: Go there!^^
For an Usagi-fan, like I am, the concert was more. Of course.

Having the latest adventures of Usagi in my mind, and watching those BIG drums in real, and hearing the thunder... great.
The musicians were so... excellent? fast?

Greetings,
