Activision is only now releasing a demo of Guitar Hero: Aerosmith to Xbox Live Marketplace. Somehow, we get the feeling that pretty much anyone interested in Guitar Hero: Aerosmith already has it. If, somehow, you're interested in this game and have yet to try it out, go give it try. Oh, one last thing, the dashboard details are priceless: "Get a taste of Guitar Hero®: Aerosmith - There's never been a band like them; there has never been a game like this." Really? Never?
