Camille and Kennerly Kitt are back, and this time they've gone dark. We've seen these identical twin harpists do the theme to 'Game of Thrones.' We've seen them do Zelda. We've even seen them cover Rihanna. Now they're focusing their attention on the Rolling Stones in this version of 'Paint It Black.'

Who knows what they'll do next? One thing's for certain -- it would definitely have weirded us out to stumble across this on a visit to the cemetery.
