I have always been a huge fan of Sci-Fi movies, and when I went to see Arrival, I was in no way disappointed. One of the greatest parts of the film was how the composer, Johann Johannsson, was able to express this alien contact movie about language and communication through the music. The music was so unique to anything that I have heard and it really gave the viewer an alienistic feel. He recorded layers of piano drones at different speeds to slow them down for one track. Then, over the drone, he brought in a singer (Robert Aiki Aubrey Lowe) and wrote a piece in which he sang uniquely over it to where it was difficult to distinguish whether it was a human voice or not. In one of the most important parts of the film, where one of the main characters has an epiphany that changes his view on life, Johann did a stellar job of capturing this moment by adding harmonic singing and overtone singing by Theater of Voices.
