Freak Me Out

Squarepusher! Wow Duane you are really branching out. You gotta check out David Torn's new album, it's kinda a freakout itself.

I am starting to sound like a broken record but - check out "Floratone", 2007 release on Blue Note. Even old people like it!

This may have been suggested, I didn't slog through all the posts, but check out Dead Can Dance "Into the Laberynth. I know that's not spelled right, but that's as close as I can get for now...
