Tens of thousands of music fans basked in the sunshine as Scotland's biggest music festival got under way.

T in the Park is expected to attract a crowd of more than 50,000 people each day to the former airfield at Balado, near Kinross.

Rain has turned the site into a mudbath in previous years, but there were no problems with the weather as the event opened on Saturday.

Oasis played at the first T in the Park festival

As the sun set, headliners Oasis, who appeared at the first T in the Park back in 1994, took the stage.

They launched into their set with Hello before moving into The Hindu Times from their latest album Heathen Chemistry.

Liam Gallagher was wearing an army camouflage jacket and clutching a tambourine throughout the performance set which also included Go Let It Out and Colombia.

Saturday's line-up also included Scots bands Primal Scream and Idlewild, along with No Doubt, Starsailor, Gomez, basement Jaxx and Badly Drawn Boy.

Tayside Police praised revellers for generating a carnival atmosphere at the event, where only 19 arrests had been made by the end of the day.

Chief Superintendent Bob Main said: "We are pleased with the way everything is going."

Scottish bands

Promoter Geoff Ellis said it was shaping up to be the best festival in the event's history.

"With the best UK line-up, a fantastic atmosphere and the finest Scottish weather, T in the Park couldn't have got off to a better start," he said.

"Festival goers are really enjoying themselves and there is just as much to look forward to tomorrow."

The Chemical Brothers play on Sunday

Sunday's big name acts include the Chemical Brothers, Foo Fighters, Green Day, Ian Brown, Mercury Rev and Sonic Youth.

A tented village with its own shops, facilities and a cinema has become temporary home to some 35,000 fans who will camp out over the weekend.

The main site encompasses a funfair and seven stages, which will play host to 100 bands over the two days.

A total of 105,000 people are expected to attend the event over the two days, making it the biggest yet staged at Balado.

However, those without tickets were being advised not to travel to the site.

Crowd-surfing plea

"The festival is a complete sell-out and if people don't have a ticket then they should not turn up," said a festival spokeswoman.

"We are confident that those lucky enough to have tickets will have a memorable weekend."

Organisers have also urged fans not to go "crowd-surfing" - where people are launched over the heads of the crowd and carried forward by the mass of people - because they say it is unsafe.

Those attending the event include Scottish Culture Minister Mike Watson, who was spending the day listening to the artists and talking to organisers about the value of major events to tourism and the economy.
