Guitarist? Bassist? Singer? Drummer? You make the choice as you create your rocker, and play the most in-depth music game yet. With the ability to play with up to four people in a band, as well as taking your band's skills on the road in the innovative "Band World Tour", the possibilities are endless. Nobody to play with? Not only are there "solo careers" for Guitar, Drums, and Vocals, but Rock Band also allows you to play with people all over the world over the internet in the online version of Band Quickplay (though, notably, Band World Tour is, as of yet, unavailable in online play).
