This Icelandic cellist has quite a collaboration resume! She has worked along side Animal Collective, Pan Sonic, Thobbing Gristle, The Knife, and Mum but just as magnificent is her solo work. She released "Without Sinking" (mixed by Valgeir Sigurðsson ) last year on Touch and this is my favorite go to record when my ears need to be given a clean fresh start after listening to anything God awful.
And a few links to her:
PS: And very much looking forward to seeing this movie and she is included in the score.
