Lego Rock Band

Lego Rock Band is a music video game and part of the Rock Band series developed by Harmonix Music Systems, but also incorporates elements from other Lego video games as developed by Traveller's Tales. The game is published by Warner Bros. Interactive Entertainment and MTV Games. The game was released on November 3, 2009 for Xbox 360, PlayStation 3, and Wii home consoles. A Nintendo DS version was also developed in conjunction with Backbone Entertainment.

The game, as with other games in the Rock Band series, allows up to four players to use instrument controllers to play lead and bass guitar, drums, and vocals on a number of rock music songs. In addition, aspects of building with Lego bricks are incorporated into the game, allowing players to customize their avatars and other band assistants, and include additional Lego-themed gameplay modes. The gameplay and the game's 45-song soundtrack has been selected to create a "family-friendly" game. Players are able to export the songs from the game into other Rock Band titles, while existing and future downloadable content that passes family-friendly filters can be incorporated into the game; however, songs released after Rock Band 3 are not compatible due to changes in the song format.

Lego Rock Band was met with moderate reviews, which praised the inclusion of both the Rock Band and Lego video game aspects incorporated into the game, but questioned some selections on the game's soundtrack and some features that would be at odds with the target audience of the game.
