The pandemic could not stop UK clubbers from getting back on the dance floor.
At least five-thousand partygoers have ditched their face masks and social distancing measures in the name of science and music.
"Feels dead weird to be back around so many people and, like, without masks, without social distancing. Honestly, it feels amazing."
This rare outdoor music festival is part of a government trial, to test the effect of crowds on the spread of the virus.
The attendees had to show proof of a negative COVID-19 test with no signs of symptoms before being allowed in.
Also, they had to promise to get tested again five days afterwards.
The director who led the pilot project said that this science-led event would play a key role in opening up the live music industry in a safe and secure way.
