[Powerslave]

Here's a list of some great stuff, excluding the bands you mentioned:

I.Q. - Ever (1993) (concise, catchy Neo-Prog)

King Crimson - Thrak (1995) (their best since Red, IMHO)

Godspeed You Black Emperor! - f# a# (infinity symbol) (1998) (very avant-garde, but really cool)

The Flower Kings - Space Revolver (2000)

Marillion - Anaraknophobia (2001) and Misplaced Childhood (1984) (great albums from the late and early Marillion eras)

Galleon - King Of Aragon (1995) (awesome keyboards; inspired by Rush and others)

Transatlantic - SMPTe (2000) (the best prog supergroup of the new millennium, but alas, they are no more)

Anekdoten - From Within (1999) (the heaviest band I've heard to come out of the Swedish prog revival of the 90's; influenced by King Crimson, but excellent for non-heavy fans too)

Citizen Cain - Serpents In Camouflage (1994) (Genesis inspired symphonic neo-prog with a vocalist sounding very close to Peter Gabriel)

Djam Karet - New Dark Age (2001) (astounding!)

Somnambulist - Paranormal Humidor (2001) (Crimson-style heavy prog, absolutely awesome! My #1 album of 2001)

Hamadryad - Conservation Of Mass (2000) (My #1 album for 2000--killer stuff!)

Ayreon - The Universal Migrator, Part 1: The Dream Sequencer (2000) (unbelievably great musicianship suited for the staight-prog pallet; if you can handle prog-metal as well, pick up Part 2: Flight Of The Migrator (2000))

Chroma Key - You Go Now (2000) (excellent album from Dream Theater's original keyboardist, but it's not prog metal--more like progressive pop)

Enchant - Blink Of An Eye (2002) (newest--and best, IMO--from this heavier band inspired by Rush)

IZZ - Sliver Of A Sun (1998) (a wide mix of styles keeps this band from ever getting stale)

Vulgar Unicorn - Under The Umbrella (1995) (jazzy progressive rock with very long tracks--superb!)


Well, that should get you started. You ought to find at least one thing up there that you like. Happy listening!
