Download Festival will hold a three-day pilot event next month, with 10,000 people expected to attend.
The event will be run as part of the government's research programme, which is assessing the best way forward with events once COVID-19 lockdown restrictions have been lifted.
Download Pilot will take place at its usual home of Donington Park in Derbyshire, and will have a capacity of up to 10,000.
Nobody at Download Pilot will be required to socially-distance or use a face covering for the duration of the event, which will run from 18-20 June.
Festival goers will be allowed to "mosh", but to get inside the event, attendees must provide proof of a negative COVID-19 lateral flow test, as well as consent to testing on the way in and out of the venue.
Download is a rock and metal music festival, and in the past has hosted headliners such as Kiss, Aerosmith and Iron Maiden.

"This massive next step will help us understand and study the safe return of large-scale festivals with no social distancing or facemasks over a full weekend… the return of the full festival experience we have all been waiting for and a much needed return to work for musicians, backstage crew, caterers and many more that form part of the UK's exemplary live music industry."
