I haven't seen the film, but if it's as evocative as the soundtrack, it should be a must-see movie. "The Revenant" features a soundtrack curated by Sakamoto and Alva Noto, long-time collaborators. Suggestion is the key word for the musical notes that move through the images. The centerpiece "The Revenant" is by Sakamoto; I haven't heard the entire work yet, but I could suggest it to @[luludia], who lately seems to be peeking through gossamer sounds, or to seasoned traveler @cosmicjoker, just to see what effect it has.
