Yes, on Thursday there are some secret sets and some massive parties, but Friday is when music starts on the main stages. This year's show was opened by Johnny Greenwood from Radiohead.
Greenwood, who has a long history with the event, was performing some of his own work including a track called 'Loop' on the West Holts Stage. He was followed by the London Sinfonietta orchestra, who played a Steve Reich piece.
The guitarist kept quiet between songs. He was greeted by a large crowd.
Kaiser Chiefs opened the music on The Other Stage. They were 'secret guests', but news that they would be performing leaked on Thursday.
Ricky Wilson bounded onto the stage as the Leeds band opened their set with 'I Predict A Riot'.
The enigmatic frontman led the crowd through a sing-a-long of their hit 'Ruby' towards the end of the set.
A rare spot of heavenly weather on Friday at Glastonbury.
Glastonbury organiser Michael Eavis was one of the people who paid tribute to Tony Benn during a lunchtime event on Thursday.
The late politician Tony Benn, who died in March, was a regular speaker at the festival and this year has had a tower erected in his honour. Glastonbury veteran Billy Bragg also spoke about the Labour party legend at the festival's Leftfield stage.
Following Kaiser Chiefs' set, legendary rockers Blondie performed on The Other Stage. Debbie Harry and co opened their set with 'One Way Or Another'.
Debbie Harry said that playing at Glastonbury was Blondie's "wet dream". Make what you will of that...
Dolly Parton has our own water supply. And people call her a diva...
The Eavis family really upped security this year to keep troublemakers at bay. Get up to mischief and you'll have this clan of ninja warriors to deal with.
And the award for best transportation at Glastonbury 2014 goes to...
Jungle absolutely smashed it in front of a packed John Peel Stage tent. The live band of the summer? You better believe it.
Jungle, bringing the heat. And the moves.
Haim played the Pyramid Stage in matching whites. Fearless, these lasses.
Yeah, you hit that drum, Alana Haim.
Here's East India Youth playing his second show of the weekend at the Wow! Stage.
East India Youth in full flow.
Drenge brought their brilliant, bluesy racket to the John Peel Stage around 2pm. Later, we caught up with the Loveless brothers to hear how they spent their recent Tory music grant on cocaine. At least they're honest.
Temples in action on the John Peel Stage.
Aww, now that's a nice view, isn't it just?
Another view of the Glasto sign, up close and personal.
Rudimental, the world's first anti-gravity band.
This is the storm that derailed the festival for a worrying 30 minutes. Scary stuff.
When it rains, it pours at Worthy Farm.
Around 5pm, a freak electrical storm hit Worthy Farm, flooding the site and causing organisers to 'power down' the outdoor stages for safety reasons. Crazy stuff.
Parquet Courts tearing it up.
A view of the crowd at Parquet Courts as they entertained the Park stage.
Wild Beasts were also in amongst the action on the Park stage, playing tracks from their new album 'Present Tense'.
Wild Beasts in their natural habitat.
Lily Allen brought her 'Sheezus' album to the Pyramid Stage around 6pm, dedicating her track 'Fuck You' to FIFA president Sepp Blatter, "one of the most annoyingly corrupt" people "in the world."
Lily also dedicated a song to her husband, who she met at Glastonbury on the Friday evening of 2009's festival. They're now married. Ain't that nice.
There's another two days to go at Glastonbury yet, everyone - no flagging just yet...
Here's Jurassic 5 doing their thang. Is that turntable big enough for you, fellas?
Jurassic 5 go in for a huddle.
Here's Interpol on the Other Stage, smartly dressed as ever.
Ironically, given how BRILLIANTLY GLOOMY the perenially downcast Interpol are, their set was basically the only one the sun came out for.
Festival rule number 236437: you might as well embrace the conditions.
Lykke Li's stormy Scandi pop went down a treat on the John Peel stage.
There she is again, Lykke Li, bringing the goosebumps.
Are you there God? It's me, Skrillex. Forgive me for my synths...
Looks like Skrillex is on a green screen, helping out with the new Star Wars film. If only.
MIA headlined the West Holts stage. Much like her attire, the set was solid GOLD.
The 'Bad Girl' herself, MIA.
If the whole brilliant pop agitator thing doesn't work out, MIA always has a career as an expert spirographer.
Arcade Fire on the Pyramid Stage, or rather their bobble head equivalents.
Arcade Fire - like Barnum's circus, but with big orchestral indie riffs. Massive.
Regine giving it some as Arcade Fire's headline set went turbo during 'Sprawl II'.
More madness from Arcade Fire on the Pyramid.
Jarvis Cocker and Steve Mackey on the ones-and-twos.
