This track was originally written by Amy Lee
as the first collaboration between her and Will "Science" Hunt, when penning material for Evanescence's third, self-titled album. Speaking to the 105.7 The Point, Lee said:
"[The song] 'Hi-Lo' we've had in the bank for a long time. I wasn't quite finished [writing it before], but it's just a song that never fit anywhere that I've been holding on to and waiting to find its right home for 10 years. So it's this weird thing that I feel very close to already that I've had to listen to with my family and my friends to now finish it out and have the orchestra on it. That's what it needed — it needed that beautiful, luscious emotion that [longtime collaborator, orchestra arranger and composer] David Campbell put on there. But I wrote that song with our producer on this album, the guy that did all the programming, Will [Hunt, not to be confused with Evanescence's drummer, also named Will Hunt]."
