I don’t know enough about music theory or production to articulate it, but in general it seems to be sad melodies and / or a certain crispness to the production.
The ultimate autumn band to me is probably The National. Alligator, Boxer, Sleep Well Beast, and High Violet are pretty much the epitome of autumn (though High Violet also doubles as a summer album, strangely).
The ultimate autumn album is probably Twilight as Played by the Twilight Singers. As soon as the temperature drops it immediately becomes one of the single most effective albums out there.
surprised they’ve never revisited the folkier elements of their early sound since. think they said in an interview that their old accordion is fucked so maybe that’s part of it
This is my go-to autumn album. An album has to sound tonally and texturally a little bit chilly, but still has a kind of ‘glow’ or warmth to it. Like you’re sitting by a campfire that’s dying out.
