Rock Band 3

Rock Band 3 is a music video game, and the third main game in the Rock Band series. Harmonix Music Systems is the primary developer for the game, with additional development by Backbone Entertainment on the Wii and DS versions. The game is published and distributed by MTV Games and Electronic Arts, respectively. As with previous games in the series, Rock Band 3 allows players to simulate the playing of rock music and other genres using special instrument controllers mimicking lead and bass guitar, drums, and vocals. Rock Band 3 expands upon previous games by including three-part vocal harmonies—previously used in The Beatles: Rock Band and Green Day: Rock Band—and support for a keyboard instrument, a MIDI-compatible 25-key unit.
