Paul Mescal and Josh O’Connor star in this Bluegrass “Brokeback,” narrated by Oscar winner Chris Cooper (perfect) as an old man of the mountains who remembers that first great love — music — and the second, a fellow he met as they searched for and collected tunes in early 20th century Appalachia.

Looks like a mashup of Maggie Greenwald’s “Songcatcher” and many a same sex romance period piece, although I do love the alliteration of “Bluegrass ‘Brokeback Mountain.'”

“The History of Sound,” directed by Oliver Hermanus and scripted by Ben Shattuck, played at Cannes and opens Sept. 12.
