Evanescence's Amy Lee joined Korn onstage last night to perform 'Freak On A Leash.'
Korn and Evanescence kicked off their co-headlining tour in Colorado last night - Evanescence took the stage first with a 15-song-set, including favourites like 'Going Under,' 'My Immortal' and 'Bring Me To Life.'
They also played six songs from their latest 2021 album, The Bitter Truth.
Then Korn took the stage with a 16-song-set, playing no more than two songs from a mix of their albums.
Korn closed the night with their iconic 1998 track 'Freak on a Leash,' where Lee joined them onstage for a surprise duet.
Check out some dusty fan footage below (the audio isn't amazing.)
It's not the first time that Lee has joined Korn for a performance of the song.
Back in 2007, the Evanescence frontwoman performed an acoustic rendition of 'Freak On A Leash' with Korn for their MTV Unplugged collaboration.
