Released in 2009 for the PlayStation Portable, Rock Band Unplugged is a handheld entry in Harmonix Music Systems' Rock Band series, adapted for a single portable device rather than dedicated instrument controllers. The game retains modes familiar from the main console titles while offering a soundtrack drawn largely from the existing Rock Band library. A portion of its tracks were made available as timed exclusives, appearing in Unplugged before becoming downloadable content for the console versions of the game. The shift to PSP required condensing the multi-instrument band experience into a format suited to handheld play, making it an accessible alternative for players who wanted to engage with the Rock Band catalog away from a television and full peripheral setup.
