Rock Band 4 is a music simulation game developed by Harmonix Music Systems, released in 2015 for PlayStation 4 and Xbox One. Players form a band of up to four participants, taking on the roles of lead guitarist, bassist, drummer, or vocalist using instrument peripherals. The game supports solo play as well as group sessions with friends and family. Building on the franchise's long-running formula, Rock Band 4 emphasizes authentic recreation of musical performance across its four instrument tracks, challenging players to accurately follow note patterns and rhythms drawn from a licensed catalog of songs. The title functions as an ongoing platform, designed to let players engage with a wide range of rock music while performing alongside others. It represents the fourth mainline entry in Harmonix's flagship rhythm game series.
