The Red Hot Chili Peppers, Calvin Harris and The Stone Roses will be the three headline acts for this year's T in the Park music festival.

Tickets are now on sale for the festival, which returns for its second year to Strathallan Castle in Perthshire.

Other acts appearing include Disclosure, Bastille, Catfish and the Bottlemen, Travis, the recently reformed LCD Soundsystem, Faithless, Stiff Little Fingers, Frightened Rabbit, Craig David, The 1975 and John Grant.

Tickets are available on the festival's website and prices have been frozen, as they have the last three years.

Harris, the Scottish DJ, songwriter and producer, returns for his first appearance at the festival since 2014.

It will be his eighth T in the Park appearance and he will headline the Saturday night of the festival.

The Red Hot Chili Peppers will return to T in the Park for the first time in a decade and headline the Sunday.

The band have played T in the Park once before when they headlined the Main Stage in 2006.

In a statement the band said: "Can’t believe it’s 10 years since we last played T in the Park.

"It seems fitting to mark the 10th anniversary of that performance with a return visit."

Catfish and the Bottlemen, a Welsh four piece, recently won the BRIT Award for British Breakthrough Act.

Frightened Rabbit said in a statement: "We are extremely pleased to announce that we will be playing at this year's T in the Park.

"It's always an honour to be there, and to be back in the King Tut's tent will be fan-f*cking-tastic. See you down the front for The Stone Roses."

Scottish band Travis make their Strathallan Castle debut this summer and will have played all three of the festival’s sites, having played the very first festival at Strathclyde Country Park in 1994, the first year at Balado in 1997.

Their last appearance was a set in the King Tut’s Wah Wah Tent at T in the Park’s 20th year celebrations in 2013.

Geoff Ellis, festival director, 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."

He added: "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 Park is 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."

George Kyle, head of Sponsorship, Tennent’s Lager, said: “Tennent’s Lager co-founded T in the Park back in 1994 with our partners DF Concerts, and we’re incredibly proud to have been at the heart of this great festival ever since.

“As the T in T in the Park, our commitment to Scotland’s live music scene has remained strong throughout the past 23 years, and we continue to support grassroots talent through our unsigned initiative T Break."

Tickets for T in the Park 2016 are now on sale.

Mr Ellis said he expects the festival to sell out this year, after it failed to sell out last year.
