I mean no offense to mainstream music, but nobody needs help finding that.
World/Inferno Friendship Society - Just The Best Party - a blend of punk and cabaret.
Plague of Carcosa - Rats in the Walls - dummy thicc doom metal
Night Tempo - Pure Baby Maker LP - future funk that brings the funk
The Ergs - Aja - sugary sweet pop punk
I'm so hyped they're on tour this summer, last time they were in my city (that I'm aware of) it was like 2007 and I missed all of their set except the closing song
tinariwen - one of my favourite songs tamatant tilay
cool as shit malinese desert blues from a bunch of former tuareg rebel fighters
Dawda Jaborteh (kora) and Stefan Pasborg (drums) performing an Ornette Coleman composition. Only 92 views on this YouTube link, and like 15 of them are mine, so how's that for obscure?

Alright idk what kinda music you're into specifically so I'm going kinda all over the place with stuff I like that doesn't seem super well known:
Fifty Grand - Necklace
BLVCK CEILING - Wvfflife
Dream on Dreamer - Violent Pictures
Crywolf - Quixote (i am alone and they are everyone)
Polkadot Cadaver - Last Call in Jonestown
Sounds of Ceres - Pursuer
Silent Planet - The Sound of Sleep
The World Is A Beautiful Place And I Am No Longer Afraid To Die - Queen Sophie For President
Fifth Dawn - Another Reason (sidenote this one particularly hits me in the feels sometimes)
Landon Tewers - Ma and Pa
L'exquisite Douleur - I'll Be Late For My Funeral
Bad Luck - Impressive Depressive
Harakiri For The Sky - Manifesto
Bilo 503 - singularita t
Milk Teeth - Brickwork
Alissic - Like
The Prize Fighter Inferno - Run, Gunner Recall, Run! The Town Wants You Dead!
Blue Scholars - Sagaba
New Years Day - Do Your WorstI just used the share function on Spotify :/ I can try to use YouTube links instead if that'd work better for you comrade?
I have no exposure to mainstream music from my undisclosed location, so apologies if any of these have become mainstream at some point, because I wouldn't know.
B0rns - Syrupy pop music of the type you might expect to hear on the radio, but exceptionally well done. I saw someone with a B0rns shirt a while ago though, so maybe he's not obscure anymore.
Chylinska - What if Ramstein was significantly better, and also their lead singer was a woman, and also they were Polish? O.N.A, an earlier band of largely the same people, is also good. Winna is a good song to start with.
Hop Along - Nobody can sing like Frances Quinlan. Get Disowned is a powerful album, and Tibetan Pop Stars is the greatest post-breakup song of all time.
Heize - Has an incredible range of emotion and singing styles. I wish I could recommend specific songs or albums but they're all in Korean so who knows which is which (answer: mostly Koreans). But you can just pick an album at random, she's great.
Japanese Breakfast - They have an album titled Soft Sounds From Another Planet which is also a very good summary of what this band sounds like. Their latest album is not very good, though. Machinist is a good song to start with.
Yumi Zouma - Japanese Breakfast has an album titled Soft Sounds From Another Planet which is also a very good summary of what this band sounds like, though Yumi Zouma is more soft and less from another planet. I'll recommend Alena as a song to start with, but just for the sake of a concrete rec.
Dark Hour by DEMONDICE. The whole EP Shut Up Get Happy is constantly playing in my head, but this song is the most comprehensible if you don't know DDK.
