Madonna will headline the Big Weekend at Maidstone's Mote Park
Up to 30,000 people are heading to Radio One's Big Weekend to watch Madonna and a host of other stars.
Mote Park in Maidstone is hosting the free event on Saturday and Sunday which also features artists including Duffy, Usher, Robyn and The Fratellis.
Kent Police have been given special powers to clamp down on anti-social behaviour in the surrounding area.
More than half a million people registered online for tickets for the Big Weekend.
A large percentage of the tickets were allocated to people living in the town and the surrounding areas.
Extra trains have been laid on between London and Maidstone and park and ride services have also been put in place.
Kent Police have urged anyone without a ticket to stay away from the area.
The Kooks, Scouting for Girls and OneRepublic will also perform on one of the four stages.
