Before his death in February 2019, Icelandic composer Johann Johannsson scored the horror film Mandy. This was 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'.
