The 2016 summer festival season just wrapped up and already attention is being turned to the 2017 batch of events. One of the marquee moments on the festival calendar each year - Glastonbury - has unveiled its first headliner for its 2017 lineup, Radiohead, to the delight of many and the surprise of few.

The announcement was made by the festival on their Twitter page and with a giant bear symbol on the grass at Worthy Farm. The symbol was spotted before the official announcement and sparked logical rumors that the band would be the first headliner.

This will be the first time Radiohead has appeared at Glasto since their 2011 "secret" set at the tiny Park Stage. It will also mark the 20-year anniversary of their seminal album OK Computer.

They were widely considered to be favorites for headlining duties at Glastonbury. Radiohead released their first album in five years A Moon Shaped Pool this past May and have been touring arenas and festival on the back of that since.

Before the more concrete rumors of their lineup inclusion, there had been chatter they would be tipped for next year's Glasto. Responding to those rumors, guitarist Ed O'Brien told BBC 6 Music via the Independent at the time: "I would love to [play]. I go to Glastonbury every year, it's my carnival."

"To be asked to play at Glastonbury again would be magic. I also think Glastonbury is like our spiritual home. It is the mother of all festivals... there's nothing like that one... It would be great to play there."

They are the first act to be announced for the 2017 edition of Glastonbury. Lady Gaga has also been another rumored name, while Daft Punk has also come up in conversations despite their insistence that they won't be touring in 2017 and the yearly touring rumors that are always false.
