Oggy oggy oggy! The donk-tacular dance music of Hull’s huge funfair

With 600,000 people attending, Hull Fair is the UK's biggest - and has a thrilling but overlooked musical subculture. We follow the blaring soundsystems to meet the DJs and MCs facing off in waltzer battles

The smell of fried onions wafts across the pink glare of candy floss, as lights pop, smoke billows and songs play simultaneously at deafening volume: walking through Hull Fair is a sensory overload.

Stretching across 16 acres and more than 300 attractions, it is one of the largest travelling fairs in Europe and will pull in around 600,000 people during a week-long run that ends on Sunday. However, despite the myriad thrills, including the UK's tallest fairground ride, there's one attraction that remains king: the waltzers. When this year's event was officially opened by the lord mayor, it was via a ceremonial bell ringing on one of these rides.
