Thousands of revellers are pouring into Brighton for Fatboy Slim's seaside gig.
The Hove based DJ is headlining Big Beach Boutique 4, which got underway at 3pm in Madeira Drive.
Around 20,000 people are expected at the event, which is ticket-only.
Fatboy Slim, aka Norman Cook, is expected to take to the stage at around 8pm and play until 9.45pm.
People from all over the country flocked to see the spectacle.
People living in Brighton and Hove have been given priority for buying tickets but they have been bought up elsewhere with many making use of the internet sites such as Ebay to purchase them.
Brighton train station was busy throughout the morning, with warm weather also boosting visitor numbers to the city generally.
Brighton and Hove City Council has urged those without tickets to stay away from Madeira Drive to avoid overcrowding.
It is the fourth time Fatboy Slim has held a huge open air concert in the city.
Organisers have been careful to limit numbers following Big Beach Boutique II which attracted 250,000 people, leading to some criticism.
