The "Band" plays on in this follow-up to the chart-topping, peripheral swapping Rock Band. Once again up to four friends can jam together on drums, lead vocals, guitar, and bass as they choose from a number of licensed songs from rock's biggest artists. The "World Tour" mode from the first game expands to new venues and now includes the ability to embark on a solo bass tour in addition to gigs with the other instruments. This mode is also no longer as restrictive, allowing friends to join in or leave at any time, custom characters to switch instruments, and more.
