I really loved the soundtrack to pic related, are there any albums with a similar sound?
you might like some John Cage's piano pieces (not 4'33" and not the prepared piano stuff). They're more "harsh" than the BotW Hyrule field theme but they still have the same sparseness.

skip to Seven Haikus, In A Landscape, and Dream
literally just buy a keyboard and play some chords

My favorite video game soundtrack is the Fable 2 soundtrack by Russel Shaw. It's a bit different from the Zelda one, but it's amazing.
