Their one my new favorite bands. They call themselves fantasycore. Each of their albums tells a story. Their early albums have more of a D&D/Tolkien feel while this newest album has more a sci-fi feel to it.
No offense but the way you're both headbanging reminds me of when you show your crush a song you think they'd like, but you actually hate it and they hate it too but you both pretend to like it thinking the other does.
