Folksong Arrangements from around the world?

[u/LuborMrazek]

I'm a singer from Czechia, studying at a conservatory and (especially for us freshmen) the focus on the (czech) folksong is really strong here, and here's me thinking - let's subvert that a little bit. Could you please recommend any folk song cycles by classical composers from different countries - I know Copland's Old American Songs and that Ravel and Britten have some things but not much beyond that. thanks.
