All the best pictures from Friday at Glastonbury 2013, including Arctic Monkeys, Haim and Nile Rodgers. Late in the night Radiohead's Thom Yorke played a secret DJ set along with Nigel Godrich in Shangri-La.
Before that, Arctic Monkeys played an explosive headline set on the Pyramid Stage. Afterwards they told NME they "couldn't have given it any more".
Some fans let off flares in the crowd. Tens of thousands of people watched the Monkeys' performance.
Highlights of Arctic Monkeys set included Alex Turner singing 'Happy Birthday' to his mum and a guest appearance from Miles Kane for set-closer '505'.
Chic's Nile Rodgers played a variety of his hits that he's written and produced including Madonna's 'Like A Virgin' and Sister Sledge's 'We Are Family'.
His set ended with fans being invited up on stage.
Alice Glass from Crystal Castles dived into the crowd despite apparently suffering from food poisoning earlier in the day. Could have got messy.
The young brothers Disclosure brought Jessie Ware, Eliza Doolittle and Aluna Francis on stage with them at Sonic in the early evening.
As expected, the crowd went off when they played hit single 'White Noise'.
The Vaccines played the third slot at the Pyramid stage before Dizzee Rascal and the Arctic Monkeys.
Dressed in a black denim jacket, frontman Justin Hayward Young said: "OK Glastonbury, hands in the air, oh yeah" before a rousing version of 'Wetsuit', which saw the crowd clapping and singing along
The London-based band also played a host of songs from their second album, 'Come Of Age', including 'Teenage Icon' and 'No Hope'.
Alt-J played a set at the Other Stage which included lush new ditty 'Buffalo'.
Palma Violets' Glastonbury debut was a roaring, ramshackle success over on the Park stage this afternoon, pulling in a respectable crowd despite stiff competition from Tame Impala and The Vaccines.
"You're not watching fucking Tame Impala, are you?" sneered bassist Chilli Jesson by way of an introduction, before careening into opener 'Jonny Bagga' Donuts', setting the pace for a gig that, even during quieter moments like 'All The Garden Birds', seemed to move at 100 mph.
Jesson and co-frontman Sam Fryers were their usual rambunctious selves, bantering with the crowd and seeming to make it through the likes of 'Rattlesnake Highway' and 'Tom The Drum' by "the seat of their pants and the skin of their teeth", before the set peaked with a mass singalong to 'Best Of Friends'.
Solange brought hit 'Losing You' to Worthy Farm.
Contender for best outfit and hair of the weekend, for sure.
Fatboy Slim played a secret DJ set, one of a whopping six at the festival this year.
Skrillex turned up as a surprise with Blood Dog, his side project with Boys Noize.
Miles Kane ripped through a 45-minute set at the John Peel tent in the early evening.
Fans were spilling out of the tent in order to get a glimpse of the show. He was joined on stage by his Last Shadow Puppets bandmate Alex Turner, hours before Arctic Monkeys headlined the Pyramid Stage.
Enter Shikari, a somewhat unlikely sight at Glastonbury, performed a mid-afternoon set on the Other Stage.
Things got a bit raucous.
Members of the band ran down to the front of the stage and started beating large plastic bins.
Crackin' air-time from Pelle from The Hives.
The Hives rocked the Other Stage with brio. Those high kicks give Jarvis Cocker a run for his money.
Swedish Howlin' Pelle Almqvist channelled Pearly King.
Jake Bugg played the Acoustic Stage in the afternoon just after his first Pyramid show.
Jake Bugg debuted two new songs and included a Neil Young cover in his well-attended afternoon Pyramid Stage set. The first new track was a dark, moody, rocky number featuring the lyrics, "There's a lot I need to tell you there's a lot that you should know/Oh, anyway, it's been a long long day".
Jake Bugg told NME: "After I do my set on the Acoustic Stage I've got to go to Switzerland or somewhere for another gig, which seems a bit of a shame, but then again I hate festivals anyway. So I'm kind of buzzing at the same time."
The second, 'Slumville Sunrise', was a more frenetic country-rock stomp. After an acoustic section with stripped-down takes on 'Country Song' and 'Broken', Bugg covered Neil Young's 'Hey Hey, My My (Into The Black)', before closing with 'Lightning Bolt'.
Haim drew the first big crowd to the Pyramid Stage at this year’s Glastonbury festival, with a 12.30pm set following Malian musician Toumani Diabate.
The band opened their set, which was almost an hour long, with 'Better Off', before playing the singles 'Forever' and 'Falling' as well as 'The Wire' and 'Honey And I', which are thought to feature on their forthcoming debut album.
"I think this is the best moment of my life right now," said bass player Este Haim after their raucous rendition of Fleetwood Mac's 'Oh Well', beckoning their tour manager onto the stage to take a photograph of the band and document the moment.
At one point, Este left the stage, returning looking shaky and telling the crowd it's "the problem with being diabetic". She then performed two songs sitting down, and Alana Haim asked the crowd to "give it up for that trouper over there".
Swim Deep played the John Peel Stage, their first Glastonbury outing.
The music at Glastonbury 2013 has officially begun. Liam Gallagher's Beady Eye were one of the first bands on, playing an unbilled show on the Other Stage. The secret was clearly out though, as thousands of people turned up to watch.
Their set was something of a U-turn since Liam's publically criticised Glastonbury in the past. Speaking from the stage during 'Rock 'N' Roll Star', he said: "Tonight, I'm a rock 'n' roll star – at 11.30am in the fucking morning!"
