It's apt that Hot Hot Heat bound on to Delia Derbyshire’s amazing 'Dr Who' theme at the start of their headline set.

Tonight is like stepping out of the Tardis into the week into 2003 when punk-funk was de rigueur - the days when MySpace was the self-set radius around you on a dancefloor, nu-metal was still considered something of an art-form and this writer was barely old enough to get served for cigarettes down at Spar.

Yep, much has changed since those days – not least the fact that The Pigeon Detectives are now everyone’s favourite afro-ed indie goons – everything, it would seem, apart from these Canadian fun pups, who tonight play the majority of their debut album 'Make Up The Breakdown' like it was released last week, rather than half a decade ago.

Thing is, we’d forgotten just how many of their bouncy punk-funk tunes we got drunk to when we could sneak into our local indie disco all those years ago – 'No, Not Now', 'Elevator', 'Naked In The City'.

Steve Bays still jerks around the stage like a man with a colony of cockroaches in his crotch, too.

And it has to be said that few songs can transform a tent into a sea of wild dance-spasms better than 'Bandages'. Tonight, as ever, it’s their undoubted highlight – a welcome, jerking blast from the past

That said, there is a mass exodus from the tent after they play it – guess times change, but Hot Hot Heat will only ever have one song the majority of a festival crowd will want to come and dance to.

Best Song: 'Bandages'

Best Moment: Erm, 'Bandages'.

These Chicago emo-rockers are apparenly Pete Wentz's favourite band - the Fall Out Boy tool even lobbied for them to get signed to his band's label Fuelled By Ramen.

It's not hard to work out what Wentz sees in them, either - they have great cheekbones, perfect hair and teeth and a sackful of stadium emo tunes so identikit that we're convinced they were conceived at a record label board meeting entitled Bridging The Gap: How We're Gonna Make Money Between Panic! At The Disco and Fall Out Boy albums.

Not that a packed Carling Tent seems to notice - there's not a dry pair of knickers within a hundred yards of the place.

Best Song: 'The Phrase That Pays'

Best Moment: The entire tent handclapping during 'Black Mamba'.

If these New Yorkers really are responsible for inventing a whole new genre - puzzle-pop - then the puzzle in question is a Rubik's Cube.

Chiefly because you need HUGE patience to listen to them.

Guitars twitter. Synths cough their guts up like The Mars Volta with emphysema. Drums stay resolutely out of time.

Then the great Glitter Band beat of 'Atlas' kicks in, the tent errupts into raptures and the Rubik's Cube's completed.

It's a set best summed up by two punters we overhear arguing on the way out: "Wow, that was amazing, like Miles Davis-style shit," coos one.

"Nah mate, it was TOTAL bollocks," says his mate in The Enemy T-shirt.

Best Song: 'Atlas'

Best Moment: When the band's 'fro-ed guitarist swung his instrument round like a baseball bat.

Cloaking the stage in dry ice and giving their footwear a good eyeballing, these West Coast Pumpkins-obsessed rockers spend their set less playing songs and more chugging out one half hour long riff.

But what a riff: as blissed out as a weekend getting shroomed on a beach, as prickly as Pete D surrounded by female paps.

It all comes together on 'Well Thought Out Twinkle' when the half-full tent wakes up, realises it's heard the tune before and gives the SSPs the rapturous respect they deserve.

Best Song: 'Well Thought Out Twinkle'

Best Moment: Realising they can do Smashing Pumpkins better than the Pumpkins can themselves these days.

It's rumoured that this LA electro-emo group's singer Carah provided the vocals for Paris Hilton's album.

Frankly, this is pretty much the most interesting thing we can tell you about this lot - imagine Paramore ditching all their amazing bubblegum-pop tunes in favour of dreary synth rock.

That said, they do pull in one of the days biggest - and most predominantly female - crowds, who chant Carah's name and squeal with delight at every available moment.

Best Song: 'You Are The One'

Best Moment: The Netto sign held by a fan down the front - an apt supermarket metaphor for this dull emo fodder.

Any band that writes songs about robots, spaceships and hair-brained scientific experiments is going to be inherently more interesting than 99% of the indie nation.

That Tokyo Police Club - four geeky looking dudes from Toronto - marry this to a bevy of bouncy, jaunty guitar pop tunes is only a bonus.

Dave Monks' voice creaks with emotion at every turn. Guitars jostle, swoop and soar. A keyboard weeps in the corner.

And NME's heart explodes into a million tiny pieces.

Best Song: 'Nature Of The Experiment'

Best Moment: When the band shout out their name during the opening song. All bands should do this.
