 " Hills of Radiant Wind " is one of the few upbeat songs on the largely dark soundtrack ; for that piece Evans sang in a version of Portuguese in a style meant to sound like a spirit floating on the wind . For " Grandma " , she sang in a French style , trying to " put in as much anguish and melancholy " as possible ; she created the song in a single recording , and it is " one of the most memorable songs " that she has sung . " The Wretched Automatons " is sung in a variant of English and was recorded prior to the addition of the mechanical sounds that run throughout the track , while " Kainé " is in a version of Gaelic .
