This a street party with thousands of revelers jamming behind music trucks in the early hours of the morning.
Also known as 'Mud Mas' revelers daub themselves with paint and mud and do their best to similarly daub their friends.
It's a lot cooler at that time of morning!
Plenty of food and drink available.
Organised by the National Cultural Foundation (NCF), the event is expected to attract many bands of registered revelers. There'll be many 'unregistered' as well!
Security is provided.
There are three starting points:
Queen's Park, Bridgetown
The BIDC, Trevor's Way
It ends as usual at Spring Garden.
