Just three days ago, soundtrack composer Clint Mansell posted these 17 tracks under the collective title Shhhhh!, combined with a “Shushing Face” emoji, to his SoundCloud account. A commenter on the opening track, “Don’t Say a Word,” asks if it’s the score to Ghost in the Shell. However, a quick check of the titles seems to confirm what the collection’s title, in retrospect, suggests — that this is the music from Mute, the film by Dunan Jones that debuted on Netflix earlier this year. There’s a snippet of what is said to be the Mute end-credits score on YouTube from back in February, and it is identical to the “I Would Drive All Night(Slight Reprise)” track here (the final one, number 17). Another clue: the penultimate track includes the name “Leo,” the Mute lead character, played by Alexander Skarsgard (except in flashbacks to him as a young boy). The set was originally posted at soundcloud.com/clint-mansell. He announced it, coyly, on Twitter, and though someone there guessed it as the Mute score, Mansell hasn’t replied as of this writing.
