The world's biggest girl band, Blackpink made history on Sunday by becoming the first K Pop act to headline a British music festival.

If you don't have a 'tween daughter, you might not have heard of Jisoo, Jennie, Rosé, and Lisa, but thousands of fans flew in to catch their high-energy well-drilled routines to social media-fuelled thumping electronic dance hits.

With over an hour and a half to wait between support act Sabrina Carpenter and the main event, the anticipation was feverish, with screams every time a roadie came on to jiggle a plug.

What with the fireworks, popping streamers, and costume changes - props to the design team who conjured myriad versions of sequinned underpants - the tight 80-minute set left little time for speaking.

'Hyde Park go crazy' was an early cry, well not in the sense of the spontaneous spirit of rock'n'roll, but in terms of frenzied screaming and waving offical merchandise light sticks, well yes.

It's quite a show, manufactured by multinational entertainment titans YG, the quartet were put through six years of strict pop-star boot camp before being unleashed on the world in 2016.

Like elite athletes - or circus performers - their ability to rap and sing note perfect while snapping out expertly-executed complex moves is phenomenal. Slick, frenetic renditions of hits Pink Venom, and How You Like That, Pretty Savage and Kick It whipped up the crowd before each girl has a solo number; Jennie with Solo, Lisa with Money, Jisoo the love song Flower, and Rose with On The Ground.

The quartet perform as much to the cameras that feed the giant screens as to the crowd - with garish back projections, a runway, and eight-strong dance teams, at times it feels like a live music video.

And if the grrl power snarls and kicks feel like part of their pop persona, by the finale of DDU-DU DDU-DU and Forever Young they finally break some emotion sweetly overwhelmed by their Hyde Park reception.

"We didn't expect this much energy from you London".

If the crowd's reaction is anything to go by this won't be the last huge K Pop gig the UK will see.
