Itching to get a taste of Guitar Hero Metallica?  The upcoming Guitar Hero title must have turned more than a few heads when first announced, and now curious fans can try it out on Xbox LIVE.

As of today, the Guitar Hero Metallica demo will be available for free download from the Xbox LIVE Marketplace.  The demo includes hit songs "Sad but True," "Seek and Destroy," "No Excuses," and "Stone Cold Crazy," from Metallica, Alice in Chains, and Queen; the latter two were hand-picked by Metallica to be featured as guests in their game.
