Everywhere at Once is funded by the National Lottery and delivered by Music Venue Trust, Save Our Scene and The Association of Independent Promoters.
Artists including Fatboy Slim, Becky Hill and Rizzle Kicks will take part in the festival across the country.
“We’re all kind of feeling the same thing, these venues have been a part of our lives,” Tempah said.
“It would be a shame to lose institutions that have almost been a gateway for artists like me to get as far as I have done.”
According to the Music Venue Trust there are more than 800 grassroots music venues in the UK and 53% showed no profit at all in 2025.
The Everywhere at Once organisers said: “With Glastonbury taking a fallow year in 2026, we saw an opportunity to create a national moment that shines a spotlight on the places where live music begins – the venues on our high streets, in our towns and cities, that give artists their first stage and audiences affordable unforgettable experiences.”
