Your favorite prog rock music? ?

All the above (except the Cars) plus a few more I have in my collection:

Egg
Henry Cow
Slapp Happy
The Nice
Van der Graaf Generator (alluded to by Audiofeil)
Procol Harum
The Enid
Osanna
Kansas
Spocks Beard
Liquid Tension Experiment
Mars Volta

and a few who are maybe classified as Prog Jazz or Fusion but I feel can be concidered Prog Rock:

Dixie Dregs
Mahavishnu Orchestra
Jean-Luc Ponty
Return To Forever

Triumverat, Grobschnitt, The Nice, Van de Graaf Generator.

Very highly recommended:
Triumverat - Illusions on a Double Dimple, Spartacus
Grobschnitt - Rockpommel's Land

I've got one record of the others but haven't listened to them in years. Time to fire up the record cleaner.....

I think someone needs to define Progresive Rock. I always felt it was when other elements or styles of music were introduced to Rock n Roll. Example side two of King Crimson's Lizard or Moody Blues Days of Futures past.

hugg, manfred mann's chapter 3, 801, anything on vertigo(the real 'nirvana') or harvest gets in and up front.
