I was reading about this game in the current issue of
Game Informer .
Jack Black ( Tenacious D ) voices the main character named Eddie Riggs .
Inspired by Eddie, The Iron Maiden mascot and Derek Riggs the artist that originally drew him up.
You get transported to a fantasy world where you wield a giant Battle Axe and a Guitar ( Secondary Weapon ) that you use button combos for different combo attacks.
The animations are somewhat of a mix of Japanese art, Guitar Hero style characters, Some
Kiss Makeup and a little Claymation.
Another thing that caught my interest is that it's also loosely inspired by the 1981 movie
Heavy Metal.
The game trailer even has a song from one of the movies battle scenes.

BTW
If you haven't seen the movie
Heavy Metal you really should. Excellent animation , boobies , brutal violence , a stellar voice cast, and probably one of the best movie soundtracks ever. stay away from the sequel
Heavy Metal 2000, it's terrible.
