A bird chirping… masked men performing a ritual… what does it all mean? That's what Radiohead fans are asking themselves on Tuesday morning (May 3), after the band shared a pair of mysterious teaser videos on Instagram.

Both clips appear to be claymation, and the first one features a small bird singing on a branch, while the second one shows a woman tied up as men with swords ominously dance around her. Neither video includes a caption.

Over the weekend, Radiohead disappeared from social media, deleting all previous postings on their accounts. That came after the band sent bizarre leaflets to fans in the mail.

The follow-up to 2011's The King of Limbs does not yet have a release date, although rumor has it that it will drop in June. Radiohead has a bunch of world tour dates in place, including stops at Lollapalooza and Outside Lands in the U.S.
