Lionel (Paul Mescal), a student at Boston’s Berklee College of Music in 1917, meets David (Josh O’Connor) at a bar where the latter is amusing himself at the piano. We learn Lionel has a beautiful singing voice. There’s a lot of singing in The History of Sound, with a particular focus on melodramatic ballads about grief and family. That would be too uncomfortable, and The History of Sound is tidy to a fault. The bigger issue, one that upends the goodwill of the whole thing, is how The History of Music is an anti-epic.
