Ad Astra - Original Motion Picture Soundtrack. A strange example of collaboration in the genre, which I think I'm noticing more lately. This is a compilation not only of music from the film, but of similar music composed separately as far as I can tell. It's nice - and makes this "soundtrack" about as long as the film itself. At least one piece from the film is missing, though - evidently released separately on its own as a single from the film.
