Great music few are aware of. Any genre.

Gorecki: Symphony #3 (of Sorrowful Songs)  Available on vinyl as the soundtrack of the French movie 'Police'.

David Hykes / New Harmonic Choir: Hearing Solar Winds

For rock try Mia Dyson - "Parking Lots" and "Struck Down"
For blues try Trampled Under Foot - "Badlands"

Allison Pierce - Year of the Rabbit

I found this one in Tidal’s Folk/Americana genre.

Allison has the voice of a melancholy angel. She writes nice melodic songs. Great album, IMHO.

For you vinyl folks, Amazon has this on vinyl and it was recorded in computer free analogue mode.

Hi inna,  Get Dream theater,  images and words,  Get the best recorded version,  this is progressive rock, How ever,  you will find out what your system is made of, 🎼🎶🎵

Visible Cloaks - Reassemblage

Juana Molina - Halo

And if you're not into wide spectrum electronica titles and into guitar tones and a dynamics work out, I HIGHLY second the Blake Mills - Heigh Ho recommendation. Room sound + insane engineering plus incredible musicianship and songwriting.
