I know PFM a little... but there is a junk techno band called PFM too. Every time a look for PFM on the web or file share programs this band appears, so i've given up.
I like prog very much! Specially King Crimson's In the Court of the Crimson King and Lark's Tongues in Aspic. I like Yes too. The albuns Relayer and Close To The Edge are great! I'm also a big fan of all Pink Floyd stuff. Prog Rox!
