A band reunion occurs when a musical group that has disbanded or gone on hiatus comes together again to perform or create new music. These reunions can be driven by nostalgia, the desire to reconnect with fans, or the opportunity to celebrate a significant anniversary of an album or tour. Reunions often attract significant media attention and can lead to successful tours or new recordings. Some famous examples include The Eagles, Fleetwood Mac, and The Spice Girls. While not all reunions are permanent, they can reignite interest in a band's legacy and introduce their music to new audiences.
