A grassroots music festival, known as Everywhere At Once, is set to take place across the UK, featuring acts such as Tinie Tempah and Becky Hill. The festival will be held at various grassroots venues, with Tinie Tempah expressing enthusiasm for the event and emphasizing the importance of supporting these venues. The festival is part of an initiative powered by the National Lottery, and will include over 2,000 artists, although the exact details and scope of the event are still emerging.
