Evanescence’s Amy Lee has premiered her first original solo song, the electronica-inflected “Push the Button.” The track will appear on ‘Aftermath,’ the soundtrack to the movie ‘War Story,’ which Lee scored with cellist and composer Dave Eggar.

Lee told MTV earlier the year that the music for 'Aftermath' is unlike anything she's done before. She explained, 'It's going to surprise my fans. It's not what you'd expect; the film is very dark, very introspective . . .”
