Coldplay kicked off the roll-out for their new music over the weekend, confirming that a double album is on its way.

On Saturday (Oct. 19), the band posted a cryptic five-second teaser to Instagram featuring an old-timey black-and-white photo of The Wedding Band & Dance Orchestra. As gentle orchestral music swelled in the background, “November 22, 1919” scrawled across the screen -- the date of a solar eclipse seen by much of the world. (Earlier in the week, posters featuring the vintage graphic started popping up inexplicably around the globe.)

The band confirmed that the mysterious old-fashioned visuals pointed toward new music by sending fans typewritten notes directly in the mail on Monday (Oct. 21). “Dear friends,” the note from Chris Martin and Co. reads, “my typing isn’t very good i’m sorry / I and we hope wherever you are you’re ok / for the last 100 years or thereabouts we have been working on a thing called Everyday Life / in the classifieds you might write ‘double album for sale, one very careful owner’ / one half is called ‘sunrise’, the other ‘sunset’ / it comes out 22 november / it is sort of how we feel about things / we send much love to you from hibernation / chris, jonny, guy and Will Champion, esq."

The Nov. 22 arrival of the two-part LP will mark Coldplay’s first studio album in nearly four years, following 2015’s A Head Full of Dreams (though the band did release a live album, Live in Buenos Aires, last year). The group's label in the U.S., Atlantic Records, confirmed the double album, but had no further comment.
