Damn. Sorry I didn’t catch this thread quicker. A few points to add (all of which are, of course, IMHO):
Typically, the music of the genre was challenging, and the performers had genuine talent. Talent and compositional ambition eventually became unseemly, which led to the dreck of the early 80’s. Ugh.
King Crimson is still very much alive and well, and, ummm, still progressing. The earliest Crimson sounds dated as well (thanks to the Mellotrons), but was amazingly daring when it came out in 1969. But the 1973-1974 albums still sound fresh to my ears: Lark’s Tongue in Aspic, Starless and Bible Black, and Red. Some rock writers have said that the last song on Red, Starless, closed the book on Prog. Crimson successfully evolved in the early 80’s - I agree with the recommendation for Discipline. Guiding light Robert Fripp thinks of Crimson as more of an idea than a group, and he continues to follow his muse. Their current releases are very heavy-metal tinged, and they were the opening act for TOOL last year. (Tool freely admits to Crimson’s influence on their work.)
I was a big ELP fan in my youth, but most of it now sounds very dated. Brain Salad Surgery was their best.
The early music of Kansas certainly qualifies, especially the three Kerry Livgren compositions on Song for America. But they moved more squarely into pop.
Same with Genesis… Nursery Cryme, Foxtrot, Wind and the Wuthering, The Lamb Lies Down on Broadway, A Trick of the Tail, and Selling England by the Pound all qualify - once both Steve Hackett and Peter Gabriel left, the Prog label really didn’t apply anymore. Certainly Hackett and Gabriel’s solo efforts qualify as well.
Some others who dabbled in Prog included Frank Zappa, particularly in his One Size Fits All/Roxy and Elsewhere period, Deep Purple bassist Roger Glover on his album Elements (which is really really really hard to find), Gong, and others. Eventually, the line blurs between Prog, Fusion, and other genres.
Someone doing cool stuff now: Mike Keneally. I think his CD Dancing is brilliant.
Shit! It only took me two and a half years to hit my 100th post!!!:smack:
