Agreed. Hopefully, a few of the instruments that they produced on the mashup video will be excluded from the real thing.

(Wtf? Musical Saw? -_-; ) Honestly though, I'm very excited to hear the REAL performance; and moreso, I'm really wanting to hear them play songs from some of the greats. (They will also be playing music from Gabrieli, Bach, Mozart and Brahms) It will be interesting to see how well they can perform live. XD
Though, I won't be buying any tickets for this one.

I'd rather just watch it online....
