Luke: Album - Spectrum, 14th Century.
Not to be confused with the video game series that takes up hours upon hours of under-employed graduates’ time, Final Fantasy is the moniker of violinist Owen Pallett and is mostly a solo project. He’s done arrangement and orchestration work with Arcade Fire and Beirut, who back him up on this song. I really like the orchestration on this, though I think this may not appeal to everyone.
