 The soundtrack to Nier is largely composed of melancholy acoustic pieces which heavily feature vocals by vocalist Emi Evans ( Emiko Rebecca Evans ) , a singer from England living in Tokyo . She is the singer for the band freesscape , and had previously worked on video games such as Etrian Odyssey . In addition to singing , Evans was asked to write her own lyrics in futuristic languages . The composers gave her preliminary version of songs and the style they wished the language to be in , such as Gaelic or French , and she invented the words . Evans wrote songs in versions of Gaelic , Portuguese , Spanish , Italian , French , English and Japanese , where she tried to imagine what they would sound like after 1000 years of drifting .
