I don’t see Explosions in the Sky mentioned yet but they’re definitely worth a listen.

Bach’s Cello Suites. Maybe try Misha Maisky.

Not knowing anything about your musical taste I’m just going to throw a handful of things out there:

Bill Evans Trio - Portrait in Jazz

Rachmaninoff’s Piano Concerto No. 3 / Suite No. 2

Philip Glass - Philip Glass Solo

Alice Sara Ott - John Field: Complete Nocturnes

Nine Inch Nails - Ghosts I-IV

Beethoven’s 5th, 7th, and 9th Symphonies. Really all 9 of them are great.

Debussy’s Suite bergamasque (third movement is Clair de lune which you’ve probably heard before).

I hope you feel better soon.

Really like Chopin’s nocturnes.

Oddball here. I like mod files and midi files :)

Booka Shade is also good.

Oh, and also Theatre Organ stuff if you have a subwoofer.

There is a whole album for Dwarf fortress that is just incredibly atmospheric guitar, give it a listen. Personal favorites: Strike the Earth and Vile Force of Darkness. They both slap so hard

I love the Celeste OST

if these trees could talk is always where my mind goes when thinking instrumental only

You could try The Endless River by Pink Floyd

From wikipedia

The Endless River comprises mainly instrumental and ambient music

I haven’t kept up with David Gilmours solo efforts but I think his post-floyd recordings are in the instrumental genre.

I don’t know how it’ll strike your mood, but the Beastie Boys did an instrumental album, called The Mix-up, and it’s very good.

I’m not sure how to describe my instrumental music taste. Maybe engaging epic fantasy music?

My top 3 are:

• The Pirates of the Caribbean soundtracks
• How to Train Your Dragon soundtracks
• Anything by Antti Martikainen - he’s a composer who has a variety of albums in different music styles that range from orchestra to celtic to rock/metal. ‘The Sound of Courage’ is probably my favorite, followed by ‘Sonic Savior’

Adagio for Strings by Samuel Barber

Are you opposed to music that uses vocal loops more like an instrument than as lyrics? If not FKJ is my go to depressed music, especially the concert from Bolivia.

Sorry if this isn’t what your looking for

Boards of Canada for some lofi nostalgia

Streets of Rage soundtrack, Sonic 1-3, donkey Kong country aquatic something is a killer

Commix - call to mind is some classic dnb, some lyrics but often looped and mixed to be more of just another instrument

Sasha - airdrawndagger, more ambient slower melodies

Tycho - dive

Anything by Philip Glass or John Williams

Cloudkicker - Beacons, progressive metal band instrumentation kinda like animals as leaders

2010 Toyota Corolla - 2003 Toyota Corolla is the new national anthem

Bohren & der club of gore for some slow noir jazz

Spokey Dokey by the SEATBELTS

And

It’s Never Too Late by Tommy Emmanuel

Also

Lazy Place by Caravan Palace

And honestly anything by Stone Rebel

Edit to add: OVERWERK does EDM-ish mixes/covers of classical music. Toccata is really good
