Prog-Rock Essentials

Progressive rock is a diverse and hard to define genre, with its fair share of crap and excellence. Here are the albums I find to be essential:

King Crimson - In the Court of the Crimson King (1969)
King Crimson - Red (1974)
Pink Floyd - Wish You Were Here (1975)
Pink Floyd - Animals (1977)
Os Mutantes - A e o Z (1973)
Jethro Tull - Thick as a Brick (1972)
Genesis - Selling England by the Pound (1973)
Sleepytime Gorilla Museum - Of Natural History (2004)
Porcupine Tree - Signify (1996)
Anekdoten - Nucleus (1995)

There's 10. Now add to the list. :headbang:

Well I don't listen to Porcupine Tree or Anekdoten anymore. I'd replace those with King Crimson - Discipline (1980) and Yes - Fragile (1971).
