Some Radiohead fans in the UK are reporting that they have received a mysterious leaflet from the band today, possibly hinting at the impending release of the much-anticipated new Radiohead album this summer.

As Pitchfork reports, the leaflets read “Sing the song of sixpence that goes/Burn the Witch/We know where you live” and are embossed with the Radiohead logo. The unsettling note may be referring to a never released song by the band, “Burn the Witch,” which frontman Thom Yorke has teased a couple times during concerts.

A lot of hype has been swirling around the new album, including the band starting two companies called Dawn Chorus in a similar move they made right before releasing their previous albums. Earlier this month, Brian Message, who works for Radiohead’s management company, claimed that the new album will be out in June and “will be like nothing you’ve ever heard.”
