The Fab Four take center stage once more in this exclusive Rock Band spin-off. More than a compilation of songs from the Beatles, the game recreates the band's historic concerts, signature instruments, and changing appearances over the span of a 12-album career. Digital versions of John, Paul, George, and Ringo will not only perform at authentic venues, but also within dreamlike environments inspired by some of the band's more colorful songs. <br><br>As with previous entries in the Rock Band franchise, the game involves playing songs by following onscreen cues with one of four peripherals: a microphone, lead guitar, bass guitar, and drums. Vocals now offer three playable parts, a first for the series, including one lead and two harmonies. A built-in vocal trainer will help you get accustomed to singing each melody, as you are able to freely switch between all three parts with a press of a button. Three microphones are required to harmonize with your friends.<br><br>Featured on the disc are 45 tracks, including "Back in the U.S.S.R.," "Here Comes the Sun," "I Feel Fine," "Taxman," "Octopus' Garden," "Get Back," "Day Tripper," "I Saw Her Standing There," "I Am the Walrus," and "I Want to Hold Your Hand." Downloadable content is also supported to expand the initial track list, with 1969's Abbey Road the first album scheduled for online distribution. Xbox 360 owners will also be able to download a system-exclusive track, "All You Need Is Love," to enhance their collection.
