It’s more than rock and roll

 

The next epic video-game battle starts this week, but it won’t be fought with laser guns blasting away at frog-faced aliens. This showdown is all about the music. Starting Tuesday, the popular Guitar Hero franchise will be facing a new rival, Rock Band, which lets players not only live out their fantasy of playing hot licks for an adoring audience but do it in a four-piece group with their friends, whether they live down the street or on the other side of the planet.
