Has been done before, yes, but this time by Takenobu Mitsuyoshi & Rony Barrak (the percussionist from the Lebanon known for his performances at PLAY!).

That was kind of cool to see.  Thanks

That was awesome.

Probably the greatest thing I've ever watched.

AMAZING!

I <3 Takenobu Mitsuyoshi!

Hehe, I love that.  Most of the intro is a lie, though.  They'd met before; I saw them both perform this exact thing at the Play Symphony in Toronto.  Ronny Barrack is the king, though, and I loved hearing him perform in the Black Main Theme and the Chrono Cross Intro that they did here.
