Green Day and the Foo Fighters are among the bands announced as headliners at this year's T in the Park festival.
Green Day played at the festival in 2002
The festival in Balado near Kinross is being held on 9 and 10 July.
Other big names performing during the weekend include Brit Award winners Keane and The Streets as well as the Prodigy and The Beautiful South.
A third of the tickets have already been sold for Scotland's biggest festival, while the rest of the 120,000 tickets will go on sale on Saturday.
Other artists already confirmed for the weekend include Embrace, Audioslave, The Killers and Ian Brown.
Organisers have promised more than 120 acts during the event on eight stages, with more names to be announced in the coming months.
Green Day last played at the festival in 2002, the year Oasis and Basement Jaxx were among the headline acts.
The Foo Fighters also made an appearance that year.
T in the Park attracts about 120,000 visitors over two days
Last year saw the likes of The Darkness, Pink and Glasgow's Franz Ferdinand rock the enormous crowd.
"The incredible success of the last two years of T in the Park has really placed the event as one of the best in the world," said Geoff Ellis, chief executive of festival organisers Big Day Out.
"The line-up, the organisation and the beautiful surroundings enable us to compete with other festivals internationally, but it is the enthusiasm and passion of the T in the Park audience that sets it apart from all of the rest, and helps us to organise an event that Scotland can really be proud of."
Organisers offered a third of the tickets for sale immediately after the 2004 event.
