Before his death in February, Icelandic composer Johann Johannsson scored the forthcoming horror film Mandy. This is Johannsson's final score. The Mandy score was co-produced by Johann and Randall Dunn. It features Sunn O)))'s Stephen O'Malley on guitar. The album was later assembled with the help of co-producers Pepijn Caudron and Yair Glotman. Johann Johannssonn is recognised as one of the best modern film composers. His score to 'The Theory Of Everything' won a Golden Globe for Best Original Score and was nominated for the same Academy Award, whilst his stunning work on 'Sicario' also earned him the Academy Award nomination for best score. His other notable works include 'Arrival', 'Prisoners' and 'The Mercy'. Directed by Panos Cosmatos and starring Nicholas Cage, Mandy is about a man who hunts the religious sect responsible for killing his wife.
