Evanescence vocalist Amy Lee has joined Tenacious D live for a two-song performance at the Louder Than Life festival.
Lee got up with the band to provide her unique take on the songs Kyle Quit The Band and naturally, Lee.
Everyone in the video, from Tenacious D to the crowd, to Lee herself looked to be having a great time and Lee took to Instagram after the show to confirm it, calling it one of the "best nights ever".
Jumping up for duets is becoming a bit of a habit of Lee's, having joined Korn onstage for a thunderous live rendition of Freak On A Leash and welcomed Halestorm vocalist Lzzy Hale for a cover of Linkin Park's Heavy.
Evanescence dropped their latest full-length The Bitter Truth to commercial success and critical acclaim earlier this year.
