I came across these when searching the web for some "exotic" composers.
Apparently their music was inspired by composers such as Tchaikovsky & Mahler.
Gonchigsumlaa has the distinction of being the first Mongolian composer to write ballet music & Choidog is one of Mongolia's best known composers.
Well, the music's a bit of a mixture really. Sounds like somewhat vapid Soviet-era stuff, rather than Tchaikovsky or Mahler. Not of much interest to me, but others may disagree. There are some excerpts available at YouTube if you do a search.
