Jóhann Jóhannsson - Arrival
In the film Arrival, Amy Adams plays a linguist trying to decode an alien language. The score was composed by Johann Johannsson, his third film collaborating with director Denis Villeneuve. In this episode, Johann breaks down a piece from the score called Heptapod B, and how, like the film, it revolves around the concept of language.
