Absolute silence. Sometimes we want to be in it, to erect soundproof walls, to be alone with ourselves, with our own inner music. But how terrible such isolation is for someone who is able to hear.
For Reuben (Riz Ahmed), the drummer of a little-known band, sound is everything. His life consists of deafeningly loud, fast and precise beats, he is a creator of rhythm. But at one unfortunate moment, the guy loses his hearing, and it is a real disaster. His planned tour comes off, his beloved singer does not know what to think of, and an operation to put implants costs a lot of money, which the musician living in a trailer has never had.
This picture perfectly demonstrates the life of a man who has lost one of his most important feelings. Through a plethora of expressive means (from the use of a hand-held camera to the more explicit aggression shown), we follow Reuben and his paranoia and go through all the stages of acceptance of his affliction with him.
'The Sound of Metal' is by no means a musical picture. It's all about the scary stuff here, about delving into the world of Reuben, whose raison d'être was loudness. The world of a man who, in his desperate struggle to be able to hear, did not understand that no technique would help, and that the surrounding reality would respond with a clear, but deaf and artificial sound of metal.
