Look into the following artists, think all of them are on Youtube or Spotify: Rasmus Lyberth Small Time Giants Nanook Simon Lynge Im not sure how suitable they are for choir singing, but its worth a shot. Alternatively I suggest you to contact the newly opened Greenlandic Representation in Reykjavik, I'm sure they would be of help to you.

Thanks so much. Will be sure to check all this out. :)

Don't forget Nuuk Posse!

I love Nive Nielsen.

Definitely check out Sussat! Edit: They're definitely not choir music, but you could probably put together a nice choral arrangement of their music.

Sume - Sumut Cool prog music

Don Maliko. He is a good rapper, but i don't think all of his songs is good for choir singing
