They keep it interesting, but until this song with just her, and not somewhat annoying Ninja, it was only in a crazy/wtf way (80% for wtf and 20% for music before this one), but this song actually sounds kinda nice for the song itself beside the "interesting" style experience.
She's not bad, don't dig metal chicks. It should be a sausage fest.
Atleast this band is better than the Ghost B.C. band you posted earlier, checked out two of their albums and read up on their live appearances. Too much cheese man
