The Scottish event, named international music festival of the year by listings website Pollstar last week, has announced a bumper programme of eclectic music acts to celebrate its 20th anniversary.
In 1994, 17,000 people attended the first festival at Strathclyde Park in Lanarkshire while this year organisers expect to host 85,000 people on each of the three days between July 12 and July 14 at the site in Balado, Kinross.
The 2013 bill includes a wide variety of music, from R&B to folk as well as dance, rock and punk.
Headliners for the main stage have been confirmed as Mumford & Sons, Rihanna and The Killers while the weekend also includes crowd favourites such as The Script, Chase & Status, Deacon Blue, Dizzee Rascal, Editors, Ocean Colour Scene, Stereophonics and the Yeah Yeah Yeahs.
World-renowned DJ Calvin Harris has been revealed as the latest act to join the line-up for this year's festival. The Scottish DJ, producer and songwriter has worked with some of the biggest names in the music industry including T in the Park headliner Rihanna.
Homegrown talent also features strongly on this year`s line-up, with Emeli Sande, The Fratellis, Frightened Rabbit, Nina Nesbitt, The Proclaimers, Twin Atlantic, The View and CHVRCHES, who are tipped to be rising stars in 2013.
Festival director Geoff Ellis said: "We are thrilled to be welcoming some of the world's greatest artists to Kinross this July for our 20th edition, with a truly diverse line-up of seminal artists, global stars and the most exciting new breakthrough talent.
"Every year, artists tell us that our audience is like no other and that they love coming to T in the Park to play in front of one of the most passionate and enthusiastic crowds in the world. Earlier this month, T in the Park was named Pollstar's international music festival of the year and I believe we have our fans to thank for this prestigious award. It's the legendary atmosphere that makes this festival special and we can't wait to celebrate our 20th year with the greatest audience in the world this July."
