Today's Rocktagon theme is girl on girl! Two amazing chick rockers going head to head. The first one that came to mind when I decided to do this theme was Lizzy Hale of Halestorm. She is amazing live and I love every Halestorm song. Then I had to think of someone who can match Lizzy's awesomeness and Amy Lee came to mind of Evanescence! So watch both videos, which chick does it better? You decide!
