In the fall of '74 WNEW in NY was still a great underground progressive rock station. One day, driving to work I heard this back to back with a cut from Hamburger Concerto. Only just recently showed up on Youtube.
If this Chopin Prelude seems too slow for you...jump ahead to about 4:30, it picks up fast. Or got to about 6:00 when the guitar kicks in.
There's this one, too.
Yes....bonging is highly recommended for this shit!
