Rock Band Unplugged

Rock Band Unplugged is a 2009 rhythm game developed by Harmonix in partnership with Backbone Entertainment, published by MTV Games, and distributed by Electronic Arts for the PlayStation Portable. It is the third installment in the Rock Band series and the first to be exclusively developed for a handheld console. The game was released in North America and Europe in June 2009. The core game is functionally similar to the note-matching gameplay of Harmonix's previous titles, Frequency and Amplitude, with the player responsible for playing all four instruments-lead and bass guitar, drums, and vocals-using the Portable's controls.
