What song or album is the "final boss" of prog rock?

there was a reason people died in the Punk Wars wasn't there? Please tell me it wasn't all for naught.
& that's like 5 years after Pawn Hearts .
So anything made in the genre after taht was fighting a losing battle already? Were they aware of that?
I think sell by date would be around 73 for me and people were still continuing to work in the genre way after that I thought.

you could interpret "final boss" as the big, challenging moment before you finish the game (prog rock) and move on to another game (another genre), in which case the final boss might be an LP which bridges prog rock and jazz fusion, or one that leads to on to post-rock.

I kind of wish people would stop linking prog with punk rock. People, usually prog rock fans, talk as if punk was obviously a reaction against prog and that's why it happened when that's not obvious at all. Prog had already run out of steam by the time punk came along, its best days were gone - or rather the best days of its leading exponents were gone. Which introduces another possibility: that punk happened, not because prog was too elitist and complex or whatever, but because it wasn't very good anymore!

Prog and punk are not so different in a surprising number of ways. They both fit as knuckle tats for one

After 1976 no one ever heard from Genesis or Yes or Rush again

agreed, i feel like we need to do more work linking prog with disco!

See "Warm Sporran" by Jethro Tull, prog folk disco:

Actually to make that clearer when I first wrote that the then refered to wad intended to be in reference to Pawn Hearts which is 1971. So still not able to work out how the term final boss applies.

Also Punk Wars is a semi sarcastic joke that inevitably becomes progressively funnier every time it's used.

Not a crowded field once we get past the Mascara Snake and Supertramp.
