It is a nice chilled vibe with people of all ages, but I think it's only fair to mention the alcohol limits which are strictly enforced, and are a stupid pain in the ass.
The Pyramid has always been a bit Radio 2. My first festival saw Jools Holland, Jimmy Cliff, Macy Gray, David Gray, Sugababes and Turin Brakes on there. Whereas last year it had SZA, Burna Boy, Janelle Monae, Little Simz, PJ Harvey, LCD Soundsystem and Seventeen playing.
