Jóhann Jóhannsson's sudden death saddened all the fans of film music. Before his death, longtime Dennis Villeneuve's collaborator managed to finish work on the score for "Mandy", horror film directed by Panos Cosmatos and starring no one else than Nicholas Cage. The score will be released posthumously via Lakeshore on 14 September. The Mandy score was co-produced by Jóhann and Randall Dunn. It features Sunn O)))’s Stephen O’Malley on guitar.
