If that's actually the inspiration for the band's name, it wouldn't be the first time Kamelot did that. See also: Epica (after the Kamelot album)^^ Yeah, I know Melissa's covers, she also did March of Mephisto, one of the words Shagrat says at the end of the intro is "Ad Infinitum" and you know Melissa's main band's name.
Kamelot - March of Mephisto
Of course I know Liar Liar, to the horror of some I growl along with Alissa now and then..
The Dark Side Of The Moon song was really nice, really awesome sideproject.
Oh and some screamy metal!
INFECTED RAIN - Dying Light
