Festival Director Geoff Ellis said: “We’re incredibly excited to announce some of the world’s greatest artists for T in the Park today. Red Hot Chili Peppers are quite simply one of the biggest rock acts of our time, and their long-awaited return to the festival after 10 years is going to be pretty special. We’re also thrilled to welcome back a real T in the Park favourite - Calvin Harris - as our Saturday night headliner. Calvin headlined the Main Stage in 2014 and was introduced on stage by Will Smith, and for many in our audience that moment is up there as one of the most unique and special in T in the Park history.

“We’re also really thrilled to have LCD Soundsystem headline the BBC Radio 1 Stage – their reunion is one of the most hotly anticipated in recent years, and their appearance is a big coup for us.

“Artists from across the globe tell us year in, year out that T in the Parkis one of their favourite festivals to play because of the unbeatable welcome they receive from the crowd, so we’d like to say a huge thank you to our audience for the massive part they play in making this festival special. We've been working hard on getting everything ready for the fans’ arrival in July and have made some changes to the site, with the Main Arena now a quarter bigger in size and the campsite increasing by a larger amount. We hope you are all as excited about the line-up as we are, and we can’t wait to see you all this summer.”
