This is starting to get complicated!

Progressive rock evolved from psychedelic rock, the two can and do overlap, Floyd is a good example, so is Gong.

Perhaps this will help.
I Know What I Like: Trollheart's History of Progressive Rock and Progressive Metal

I did make a "prog guide" thread many ages ago and I'm not digging it up because I'm 100% certain it's cringe as all f*ck and I will actually die of embarrassment.

ProgArchives used to be my bible for a while, it was how I got into a lot of prog and it had some helpful guides but it's pretty outdated now, they badly need new categories like one for progressive pop which is a term that's very commonly used and accepted now but because that site is run by old farts who still insist prog and pop are mutually exclusive that will never happen.

Also their decision to rank an artist's entire discography under the same category (no matter how diverse it is) is really dumb even if it's supposed to be for the sake of convenience, Kind of Blue is their highest rated "jazz rock/fusion" album, what a mess.

That is because people make it complicated, they have a real bad habbit of involving what shal we say, The re-invented immitation of proper prog

:finger:

That's good to know. I'm just happy to enjoy the music.

I read some of it. I haven't gotten through all of it yet.

I bought a Rush boxed set today. I now have the set of boxes (the Sectors set). I can't wait to play all of the albums, in chronological order, of course!
