Blimey, are we having this discussion again? Transatlantic dude, it says you've been a memeber of the Moon since... This month. Somebody's got to be mean, so it might as well be me. Don't show up somewhere and on your first day start criticizing it with your narrow definition and try to sound authoritative. The official workers at this station (Avian and ProgDirJim) and to a lesser extent the lesserlings (Roger.Lee, theoriginal_ib, ExtendedPlay, myself...) have worked hard to make this station the number one progressive rock station on the net. AM's been around since 1999 (or earlier) and has a huge library. If you'd care to do a little research, such authorities as AllMusic.com and The Gibraltar Encyclopedia of Progressive Rock lists literally dozens of subgenres. So until you are well versed in Kraut (Neu!, Kraftwerk), Neo-Kraut (To Rococo Rot), Canterbury (Gentle Giant, Soft Machine), Modern Experimental (Godspeed You Black Emperor!, Blue Man Group), Pop-Prog (Journey, Styx), Post-Rock (Mogwai, Tortoise, Billy Mahonie, The Letter E), and dozens of other prog-subgenres - I repeat - until you are well-versed in all of this, don't come to an established station patroned by literally hundreds of prog-lovers and tell us what is and is not progressive rock.
As for fusion, go to a research site like
All Music Guide and search for Mahavishu Orchestra or Return to Forever and look at "related styles." Guess what you'll see? "Prog Rock/Art Rock."
In other words, if you are interested in your definition of prog only, and you don't think AM is that station, don't listen. Go elsewhere.
I'm gonna request some Journey for you now.
