Earlier this month, it was rumored that Harmonix was planning on giving Rock Band the LEGO treatment after one of their senior designers accidentally let the news slip during the Game Developers Conference. However, according to Business Wire, today they came out and officially announced that LEGO: Rock Band is in the works and will be coming to home consoles (including the Xbox 360, Playstation 3, Nintendo Wii, and Nintendo DS) in time for the holiday season.

LEGO Rock Band will be compatible with "Rock Band instruments, as well as other music game controllers."

“We’re thrilled to offer another LEGO branded gaming experience that will deliver humorous and social play for families and friends,” said Henrik Taudorf Lorensen, VP of the LEGO Group. “LEGO Rock Band is built around the same values of imagination and family-friendly creative role play that is present in other LEGO videogames. It will deliver innovative new elements of game play that complement the fun of the Rock Band experience.”

Harmonix is working in cooperation with TT Games to create a new Rock Band experience that revolves around the theme of "Build a Band and Rock the Universe." It will be full of "fun, customization and humor of the LEGO videogame franchise" and its track list is comprised of chart-topping hits and other popular songs that will appeal to a younger and more family friendly audience.

So far, some of the songs that Harmonix have confirmed will be in LEGO: Rock Band are Carl Douglas’ "Kung Fu Fighting", Europe’s "The Final Countdown", and Good Charlotte’s "Boys and Girls."

TT Games are the developers responsible for other LEGO titles, including LEGO Star Wars, LEGO Batman, and LEGO Indiana Jones:The Original Adventures. Harmonix and MTV Games are behind the hit sensation, Rock Band, which has generated over $1 billion dollars of revenue in sales.
