A VJ is a performance artist who creates moving visual art (often video) on large displays or screens, often at events such as concerts, nightclubs and music festivals, and usually in conjunction with other performance art. This results in a live, multimedia performance that can include music, actors or dancers as well as live and pre-recorded video. Also sometimes called "Realtime" or "Realtime Video."
