In 2000, Lee was featured in two songs by former Evanescence member David Hodges, “Breathe” and “Fall into You”. In 2003, Lee joined artists such as Milla Jovovich and Maynard James Keenan in a discrete musical project for supergroup The Damning Well. She provided vocals on two tracks, one of which was a duet with former Filter vocalist Richard patrick, but her vocals were eventually taken off the final release because of record label issues. She also sang backup vocals on Big Dismal’s song "Believe" from their first album.
