Reading Festival

There’s not much time to dig into her deep catalogue of future-facing pop, but she satisfies the hardcore

“Time itself is a circle,” as the rock’n’roll philosopher Nietzsche once said, accurately foreshadowing Charli xcx’s only UK festival appearance this summer. Like her performance on Glastonbury’s Other Stage last year – a pyrotechnic farewell to the puke-green reign of Brat – Charli’s Reading and Leeds appearance is a not-quite-headline slot that also follows a rowdy set from grime don Skepta.

Yet in the past 14 months, everything else in Charli’s pop factory has undergone a hard reset. She’s released two albums – a grandiose, gothic soundtrack to Emerald Fennell’s adaptation of Wuthering Heights, and last month’s high-concept Music, Fashion, Film, an album of raw, glitching micro-rock, with guitars shredded into Tetris-like pieces, and fitted with lacerating lyrics about shopping, egotism and mortality. She’s also launched an acting career, thrown a big fat celebrity wedding and, somewhere along the way, found time to rehearse her biggest, most vertiginous show to date.

They used to mean crusties, hippies, all-male lineups, near riots and burning toilets. Now, from Dorset to Inverness, there’s a festival – and a costume – for everyone. What caused this boom? And is there a dark side?

It’s 7pm on the first day of Gala festival in Peckham Rye park and dry ice drifts into the trees as grime MC Novelist, born just miles away, raps about a south London bus. “Four eight four! Going on raw on the 484,” he spits with a grin, bouncing like the sweaty moshpit in front of him. There are already hands in the air for this hyperlocal elegy when the DJ teases the next instrumental, Skream’s unmistakable Midnight Request Line – dubstep’s greatest ever anthem.

Gala is one of the first festivals of the now overflowing British summer season. That same weekend, Black Water County kicked off the Cursus cider and music festival in Dorset, Fatboy Slim headlined the Radio 1 Big Weekend in Sunderland, and scores more fizzed into action, from Elderflower Fields in East Sussex to Devauden in south Wales, Slam Dunk in Hertfordshire, Dot to Dot in Nottingham, as well as Sidmouth jazz and blues festival and Chippenham folk festival.
