When was the video game Rock Band first introduced?
Rock Band (video game)
"Rock Band" was first announced on April 1, 2007. Harmonix CEO Alex Rigopulos said in the announcement that "Rock Band" "takes the core premise of "Guitar Hero" and expands it tenfold. It lets you create a complete collaborative band." "Rock Band" was a featured game at the 2007 E3 convention and provided one of the exhibition's highlights; Harmonix employees and Microsoft executive Peter Moore played the game on-stage, performing The Hives' "Main Offender". Moore paused the game twice when he accidentally hit the guitar's Xbox Guide button.
Rock Band 2
Rock Band 2 is a 2008 music video game developed by Harmonix. It is the sequel to "Rock Band" and is the second title in the series. The game allows up to four players to simulate the performance of popular songs by playing with controllers modeled after musical instruments. Players can play the lead guitar, bass guitar, and drums parts to songs with "instrument controllers", as well as sing through a USB microphone. Players are scored on their ability to match scrolling musical "notes" while playing instruments, or by their ability to match the singer's pitch on vocals.
