Lego Rock Band is a 2009 rhythm game developed by TT Fusion in partnership with Harmonix and published by Warner Bros. Interactive Entertainment.

It is the fifth console installment in the Rock Band series, while it incorporates elements from Lego video games.

The game was released on 3 November 2009 for Xbox 360, PlayStation 3, and Wii home consoles in the United States.

Completing consecutive series of notes will build up a player's scoring multiplier and add to the band's total Lego "studs" (equivalent to points) for the song.

The Story mode follows the player's band through their career, starting by playing gigs at smaller venues and taking requests for special performances.

[3] The story mode also includes special gigs called "Rock Power Challenges" in which the band uses the "power of rock" to complete a task such as demolishing a building or escaping a dinosaur, by playing a select song from the setlist which is in-context with the task at hand.

During each song, the player switches between the various instruments, trying to keep all four members of the band "happy"; this is done by successfully completing a series of notes for the specific instrument, and then correctly hitting a final, purple note to increase that band member's happiness.

[5] The game uses the touchpad, stylus, and face buttons of the DS, and does not require or support additional peripherals like the console versions do.

[8] Also, any songs exported from the original Rock Band and its Track Packs deemed "Family Friendly" can be used in the game.

[17] David Bowie, along with his band and a venue loosely based on his music video for "Let's Dance", also appears in the game.

[19][20][21][22] In the case of Queen guitarist Brian May, he had required that the developers represent his hair style on his Lego caricature.

[23] John Drake of Harmonix stated the presence of Pop and Bowie add "rock credibility" to the family-friendly title.

[5] GameTrailers gave the game 7.9 criticising the lack of previous features such as online play, and called the Lego presentation superficial, saying the purchase decision will lie squarely on the song preferences.
