Also, the band unveils a songbook featuring sheet music for all 11 tracks on 'A Moon Shaped Pool.'

Radiohead has announced its first gig of 2017 and -- sorry fans -- it had been sold out for over a week by the time news broke. That’s because Thom Yorke and company’s first show of the new year is at the Glastonbury Festival.

The mammoth British fest confirmed news this morning (Oct. 20) that Radiohead will be headlining on June 23 of next year. Hype was so big that Glasto sold out back on Oct. 9, before the lineup had been revealed.

Fans started to speculate Radiohead was on tap when photos of “crop circles” in the style of Radiohead’s “modified bear” logo started to pop up on social media. Then Glastonbury’s official account confirmed the news, along with the finished product.

So far, Radiohead’s Pyramid Stage set is Glastonbury 2017’s only confirmed performance. They last played the fest in 2011 and headlined in 2003 and 1997.

Last year's Pyramid Stage headliners included Muse, Coldplay and Adele.

In other Radiohead news, now you can learn the songs on A Moon Shaped Pool straight from the source (if you can read music, that is). A songbook featuring sheet music for all 11 tracks is now available in the band's online store:

Radiohead released its latest album, A Moon Shaped Pool, back on May 8 and spent a good chunk of 2016 touring behind it, though Glasto is currently its only upcoming gig. Get reacquainted with the live show with Billboard's coverage of Radiohead's 2016 concert at Madison Square Garden.
