Béla Bartók (1881 - 1945) was one of the early 20th Century composers who broke free of the harmonic conventions of the late Romantic era of music, turning to what he heard from country folk he encountered during his travels. Bartók was among the emigre composers to the U.S. who was influential in the sound of film and TV scores, despite not having worked in that realm--a shame.
Here's a 1958 recording of his "Music for Strings, Percussion & Celesta" performed by the Chicago Symphony, and conducted by Bartók's personal friend, Fritz Reiner. https://www.youtube.com/watch?v=YHTy71gyrTc (Cinematic fun fact: Stanley Kubrick made use of the 3rd movement in his movie, "The Shining.")
Bonus tracks: Concerto for Orchestra - https://www.youtube.com/watch?v=clzcGIdMaN0 (I got to play in the bass section on this piece with the SF Symphony Youth Orchestra in the 1980s.)

Final thought: Bartók is the composer I wish the producers of "The Witcher" had referenced for their series, instead of the indistinct sound I heard in the episodes I watched. The mediocre soundtrack was one of the elements that killed my interest in following that series.
