Prog anyone?

Yes, I like just about anything progressive.

Porcupine Tree, Camel, Yes, Gabriel-era Genesis, King Crimson, Pink Floyd, Anekdoten, Änglagård, Amon Duul (I and II), Frank Zappa, Ozric Tentacles, Tangerine Dream, Pain of Salvation, Ark, Devin Townsend, Opeth, Spiral Architect, Borknagar, etc.
 
I've been a fan for a very long while.... especially into Marillion (all eras, my best band ever I think), early Genesis, Jethro Tull, Porcupine Tree (In absentia is awesome), King Crimson, etc.
