I've been searching through my record collection and the Prog Archives, and truly believe there are some serious omissions here and therefore recommend their inclusion asap:

Touch

T2 a band with a 21 year gap between their 1st and 2nd albums

Polysoft, a sort of one-off Soft Machine tribute band, see:

Wishbone Ash, if only for their prog  Argus and Pilgrimage albums

Obscured By Clouds 

 NW USA Floyd-influenced band

Alkemy

Addison Project

Martin Maheux

i.e. three bands released through Unicorn Records, mixing prog and jazz rock

Jens Johansson

Master keyboardist and possibly the best around at the moment; worked with metal proggers Stratavarious, with Mastermind, Jonas Hellborg, Yngwie Malmsteen and released several solo albums  (e.g. Heavy Machinery with Holdsworth  and Fission with Shawn Lane/Mike Stern, plus one whose title suffers from my Swedish being so lacking, all I can remember is the loose English translation: Naked Two-footed Bird)

Tempest (the early 70's British band)

High Tide

Gunesh

the only Turkmanistani prog group??!!

Collegium Muscium/Marian Varga

Kraan

Kennedy

Underground Railroad

Bill Pohl

Stomu Yamash'Ta (Red Buddah Theatre, East Wind, etc)

Suntreader

Brand X precursor

Gary Boyle

Hugh Hopper

Hugh Score (Caveman Hughscore)

Guy LaBlanc

Mike & The Mechanics

Mike Rutherford

His Small day's Creep was so much more interesting than what Genesis was releasing at the time IMHO

Eddie Jobson/Zinc

Donnamatrix

In The Heath Of The Moment.........

Velvetclown, you need a post graduate course in punning, e.g. 6 hours of Monty Python videos OR some of those BBC Radio Comedy cassettes e.g. I'm Sorry I Haven't a Clue

And come on, how about some support for Mr Johansson. BTW what do you make of EST - a professional musician, friend of Isaldurs Bane and moonlights in a Malmo record store, tells me EST came into that store before a gig and bought allsort of albums, including a few prog titles. Does it show in their music?

Jens Johansson is a true keyboard genius. I heard him play on Andy West's RAMA and on one of Benny Jansson's (a good Holdsworth clone) album. He has developed a style of his own and is very virtuosic.

I agree with you about Mike's "Smallcreep's day". Everything is good in this semi-concept album : drums played by the fantastic Simon Philipps, the synths played by Anthony Phillips, the vocals sung by Noel McKenna (is it the same who produced Tori Amos' "Little earthquakes").

I second these.
