LISTEN: We speak to bands on Day 1 of T in the Park 2015
More than 60,000 revellers watched artists including headliners Kasabian and David Guetta perform on the opening night of T in the Park.
Scotland's biggest music festival is taking place for the first time at Strathallan estate in Perthshire and as in previous years has drawn some of the music industry's top performers.
Mark Ronson, Sam Smith, Rudimental and The War on Drugs played earlier to crowds in the grounds of the 19th century Strathallan Castle. Mark Ronson has been telling us how Keyonne Starr ended up on his latest single, "I Can't Lose"...
Hozier was also on stage on Friday and was blown away by the crowd... Rudimental has been agreeing with Hozier and told us that the crowd was so loud...
Festival director Geoff Ellis said: "We're delighted with how everything is going so far. There's an incredible atmosphere onsite and Prides did Scotland proud with a brilliant opening performance on the main stage.'' Prides told us they were honoured to take the opening slot... Wellies were the footwear of choice for music fans at the start of the three-day festival after mist and rain churned many of the new site's walkways into mud, but low cloud later gave way to some sunshine.
About 85,000 people a day are expected to descend on Strathallan, with performances from the likes of Avicii, Stereophonics, The Libertines, James Bay and Noel Gallagher's High Flying Birds.
Mr Ellis said: "As it's a brand new site for everyone this year, we ask fans not to assume anything and to take the time to explore and get to know the campsite and the arena.
"We're starting with a blank canvas and we want everyone to respect our beautiful surroundings and to use the bins and the toilets provided.
"Have a brilliant weekend and as always, show everyone why T in the Parkers are always named the best audience in the world.''
Organisers DF Concerts struck a deal to shift the 2015 festival following health and safety concerns about an underground oil pipeline at nearby Balado, where it had been held for 18 years.
Local councillors approved the plan in May despite opposition from some residents and environmental groups who expressed concern for ospreys at Strathallan.
Concerns were also raised about traffic arrangements for the event, and the potential for anti-social behaviour.
Police Scotland has so far made 12 arrests.
Superintendent Colin Brown said: The vast majority of people have enjoyed themselves and taken our advice and behaved responsibly.
"However, a small number have ignored that advice and have been dealt with.
Our advice is simple - look after yourselves and your friends, behave and have a good time.''
Danielle Foster, 19, from Canada said: ''It's gorgeous scenery. It's a little muddy but that's all part of the fun, it's great.
''Scotland I'd always heard is so gorgeous and there's a ton of great people here this year.''
Kasabian, David Guetta, Sam Smith and Mark Ronson took to the stage on Friday Night as organisers hailed the "incredible'' atmosphere.
Dan Haggis from English indie outfit The Wombats said: Scottish crowds are just second to none.
"Anywhere we've been in the whole world, Scottish crowds are just like over the top.''
Festival director Geoff Ellis said: We're delighted with how everything is going so far. There's an incredible atmosphere onsite.''
A crowd of about 85,000 is expected Saturday and Sunday, and Police Scotland advised day trippers to plan ahead and follow event signs to avoid travel delays.
Today's line-up includes Alt-J and Twin Atlantic on the Radio 1 stage, with the Libertines, Labrinth and The Script taking to the main stage.
Noel Gallagher's High Flying Birds will close the festival tomorrow evening.
