Biffy Clyro and Fall Out Boy are set to play Reading and Leeds.
The mammoth twin-site event has been gradually building its bill for months now, adding headliners in a flurry of media attention.
A few moments ago, Reading & Leeds added Biffy Clyro and Fall Out Boy to the bill. The Scottish rockers used 2015 as a year off, re-charging their batteries following a lengthy spell of international touring.
Biffy Clyro will roar back into contention with a Reading & Leeds headline slot, joined by emo-rockers Fall Out Boy.
The Scottish trio commented: "We're baaaaack!! We are honoured to be asked to close Reading and Leeds this summer. We had one of the best nights of our lives last time and we're going to do all we can to make it even bigger and better in 2016. You ain't seen nothing yet motherfuckers!!"
Other new names on the bill include CHVRCHES, The Vaccines, A$AP Rocky, Savages, The Dillinger Escape Plan, Lower Than Atlantis, and many more.
Tickets are on sale now.
Reading and Leeds runs between August 26th - 28th.
