Made by There I Ruined It, this mashup features Dolly Parton “singing” Slipknot’s “Duality” to the melody of her own classic, Jolene, and yes, it somehow works disturbingly well! Needless to say, as with all of There I Ruined It’s mashups, the voice in this video was digitally recreated.

Even better? The video supports Dolly Parton’s Imagination Library, a charity that gives free books to kids. So you can rock out and help a great cause. You can donate right here.
