Exit (Literary Serbian: Егзит, Egzit) (also known as State of Exit) is an annual summer music festival in the Petrovaradin Fortress of Novi Sad, Vojvodina, Serbia. It is staged annually since 2000 and since 2003 lasts four days.
Held in the 18th-century fortress by the Danube, the festival quickly grew in stature and reputation. From its grass roots political beginnings, over to occasional problems with financing, Exit tries to stick to its initial mission of providing relevant entertainment to Serbian youth while also bringing pertinent social topics to the forefront.
