I've heard Tim play a song where it starts off sounding like his other songs, then he goes into a "Big Blast of Hot Air" thing and then into a Neapolitan type thing?
Kind of like that guy with the face, and the hair, and he usually wears a shirt? Just kidding, but that's a pretty general description. The only song I've seen combined with Big Blast is Entity, maybe that helps.
Ahh... the classical thing, it's probably the one tabbed on the site as "Classical Tune". On my Winamp it's called Courante, and I don't think I gave it that name... it's somewhere on the FTP. Watch the video Rheginos and the Resurrection under the Videos section and see if it's the thing he plays in the middle.
I have yet to download that video on my whopping 56.6K modem but I think it is the classical tune, but either he's playing it in a different position or I'm just not playing it fast enough.. but thanks everyone.
