Just cos you're not into a genre doesn't mean it can't pass you by and have a near-miss, scraping off some paint as it goes by.

But if you're serious, and you enjoyed early Genesis, then you need to check out Marillion's first four albums, as well as their lead singer Fish's solo stuff. Try also Rush, Pendragon and Porcupine Tree, Spock's Beard and Gazpacho, not forgetting Peter Gabriel's solo work (early at any rate) and if you can get hold of a band called Twelfth Night's "Fact and fiction" I'd say you'd enjoy that.

As a quick list then, these, not necessarily in any order:
MARILLION
Script for a jester's tear
Fugazi
Misplaced childhood
Clutching at straws

FISH
Vigil in a wilderness of mirrors
Internal exile
Sunsets on empire
Raingods with zippos

RUSH
Caress of steel
2112
A farewell to kings
Hemispheres

PENDRAGON
The world
The window of life
The masquerade overture
Believe
Pure
Kowtow
Passion

GAZPACHO
Missa Atropos
March of ghosts

PETER GABRIEL
First four albums, all called Peter Gabriel (1977/78/80/82)
So
Us

SPOCK'S BEARD
V
The kindness of strangers
Day for night
X
Octane

PORCUPINE TREE
Fear of a blank planet
In absentia
Coma divine
Stars die
The incident
The sky moves sideways
and many more

STEVEN WILSON (Porcupine Tree)
Grace for drowning

TWELFTH NIGHT
Fact and fiction

Loads more, but that will give you some sort of grounding in some of the best prog rock out there. Anyone else, feel free to add or comment.
