The T Break stage at T in the Park has been showcasing some of the hottest new unsigned talent in Scotland.

In the past two years, the stage has helped break Scottish acts including Paolo Nutini, Amy McDonald and The Dykeenies.
This year, the line-up has been as diverse as the rest of the festival. Here are some of Saturday's best…
Hailing from Glasgow, Twin Atlantic had a tough slot, competing with local guitar gods Biffy Clyro on the main stage.
Sharing more than just a fondness for long hair and big beards, the band play a similar kind of melodic heavy rock.
It must be something in the Celtic genes as they also share a similar sound to Welsh metallers like Funeral For A Friend and Lostprophets.

They drew a large and very vocal support to the T Break stage.
So vocal, in fact, that singer Sam McTrusty didn't even bother singing the words to their last song.
Drummer Craig Neale was amazed by the size of the crowd.
He said: "Yeah it was pretty insane, I think it's the biggest crowd we have ever played to."
Guitarist Barry McKenna has more than one string to his bow, also bringing out a cello on stage during the band's half-hour set.
He said: "I only played the cello and piano until I was 16.

"It wasn't until my big cousin, who was older than me and had long hair and a beard, got me into music and I thought, 'I fancy some of that'."
Their set was a sweaty one, not just on stage but from the seething mass in front of the stage.
McTrusty ended the performance upside down in the middle of it and emerged backstage having lost both his shoes.
Marvellously chaotic, the band are in the studio recording their debut album.
The Twilight Sad
Wearing their influences on their sleeves, The Twilight Sad also drew a huge crowd so early in the day.
From all over Scotland, they are based in Kilsyth, not far from the T in the Park site.

Inspired by the likes of fellow Scots Mogwai and Arab Strap, they also sound not unlike My Bloody Valentine and Smashing Pumpkins.
A wall of noise and distortion comes from the stage as singer James Graham works the fans in front of him, almost climbing over the barrier at one point.
He described their sound as "basically folk music, but with layers of noise over the top".
The Twilight Sad have already released one album and while still fairly unknown in the UK, they already have a following in Europe and the US, supporting bands like Snow Patrol and Idlewild.
Graham admitted they have done things in reverse.
He said: "We toured America and did the big festivals over there and nobody in Scotland knew us.

"We came home and played to our mums and dads, so it's strange."
Glaring over at the Radio 1/NME stage, where The Pigeon Detectives are just finishing their set, he insisted the band weren't looking for fame and fortune.
He said: "We don't want to be festival headliners, we just want to make enough money that we can stay in a band and keep making music.
"We're recording our new album in September and that should be out next year."
From the dark musings of The Twilight Sad to the quirky retro pop of Isosceles.
They initially formed as a joke for a friend's pretend birthday music festival.
Singer Jack Isosceles, real name Valentine, said: "We were told by people that we should give it a go. Now it's a long running joke."
Isosceles played the Introducing stage at Glastonbury 2008
He smiled: "And it's getting less and less funny."
Jack Isosceles smiles. A lot. In fact, he's probably the smiliest singer over the weekend.
But it fits in well with for a band who give out plastic maths protractors to the crowd midway through the set.
Their sound takes a lot of inspiration from early 80s pop music like Orange Juice.
Isosceles were handpicked by Alex Kapranos from Franz Ferdinand to support them on a recent tour of small venues in Scotland.
Valentine said: "We don't really listen to much contemporary pop music but older stuff from the 60s and 70s.
"We're been listening to a lot of northern soul as well."
They sport some great song titles, like Guns Go Bang and Kitch Bitch.

I Threw You Out
Get Your Hands Off, with its insanely catchy chorus, turns the tables on the battles of the sexes, accusing rich girls of trying to cop a feel.
Between songs, Valentine even demonstrates a strange chicken walk-like dance that he showed off at Glastonbury a fortnight ago.
The weird thing is, he genuinely seems proud of it.
Drummer Bobby Isosceles, aka Duff, admits he's just happy to be inside the arena.
He said: "A few years ago, I worked as a security guard on the perimeter of T in the Park and I had one of the worst nights of my life.
"I had an epiphany that things had to get better and, if they didn't, at least I'm on the right side of the fence now."
The main stage surely beckons.
