Bands should quit.

Classical works were commisioned

Compositional abilities like harmonically consonant simultaneous melodies of different rhythms, and polyphony in general, are like technical skill on an instrument. Most people can learn them, but even if they do, they can't use them to make good music

The classical guys made good music throughout their lifetime, and haven't blown their loads in the first handful of works.

If Incantation quit after diabolical conquest they would have exhausted everything they could do with their ideas.

Depends.

There is a lot of filler in stuff like Wagner.

It's really a soundtrack for an opera.

With motifs....

Like a score.

But such a model wouldn't necessarily help metal, as that youthful energy, mostly irretrievable in old age, is vital to it.

Depends.

Some old guys still have it

Like?

Like the Satan guys.

They just go nuts

I'd perhaps only count Summoning and Burzum.

Alternating between nwobhm and wank every album every 5-10 years

Varg lsot it

Though their later work is much different from their old work

And isn't metal.

Summoning didn't and is kinda metal.

Sammath

The Finns. Who are totally nuts.

Sammath is the most legitimate example.

Sammath changes his style every release though

Godless Arrogance is end of the world music.

Burzum and Summoning mellowed with age

Black metal -> brutal death -> zyklon b metal -> black metal rust in peace twin guitar wank -> blizzard beasts part 2

there's plenty of bad classical

There is a ton.

especially relative to a composers own output

Even from the 1700s

People paid for it to

Yeah, @Ꜻnnihilation

Beethoven wrote a bunch of middling atuff

Paid to go see lame Symphonies and quartets

As they were bored on a Saturday

even the romantic "ultimate high art will nature etc" stuff is silly much of the time

I'm mainly thinking about how the metalguys almost exclusively make their best stuff while 18-25

That's mostly when they get to express it.
