This holiday season, Harmonix and MTV Games will release the third installment in their Rock Band game series. This one, like previous entries, will include guitar, bass, vocals, and drums, but it also has keyboards and three-part harmonies, much like Beatles: Rock Band, all for up to seven players simultaneously. Rock Band also features a new Pro Mode, which more accurately simulates instruments. But, in addition to all the new software features, accessories developer Mad Catz is now the official provider of the instruments, including legacy instruments from past versions of the game. Check out more details on the new keyboard and the awesome six string hybrid guitar here.

According to Pitchfork, the new Rock Band will feature 83 songs and access to a library of over 2,000 songs by the time the game launches, with new music regularly added. The new game's tracklist includes classic-rock perennials like Jimi Hendrix, the Doors, and Night Ranger "Sister Christian" as well as more contemporary selections like Phoenix's "Lasso", the Cure's "Just Like Heaven", the White Stripes' "The Hardest Button to Button", Rilo Kiley's "Portions for Foxes", Metric's "Combat Baby", and Ida Maria's "Oh My God".

I'll be at E3 this week to check out this awesomeness in all its glory. To see all the announced songs from the tracklist, check out the game's website. USA Today has posted a video that includes people from Harmonix showing what the new game can do; check it after the jump.
