Sleepthief is an electronic music project founded by the American producer and composer Justin Elswick. The first album, The Dawnseeker, was released in 2006 but Elswick started writing the songs for the album 10 years before. Most notably about The Dawnseeker which Just say it comes from is that there are 13 songs with 11 different vocalists.
I think Just say it is well worth a listen. I really like Kyoko's voice together with the melodic tunes, they mix well together. She has a very beautiful voice and the song both sticks and yet not. I also really like the lyrics.
