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.
Avicii, Jessie J and George Ezra are some of the top names in Saturday’s line-up.
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 and Prides did Scotland proud with a brilliant opening performance on the main stage.”
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 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.”
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.”
