WATCH: Video for Radiohead's new single Daydreaming as album announed for Sunday
Radiohead returned with a new song 24 hours after deleting their music from the internet, have released the video for Daydreaming, and announced their album will drop on Sunday.
The British band's official website and Facebook and Twitter pages were stripped of all their content on Monday.
Lead singer Thom Yorke also deleted all material from his Twitter account, @thomyorke.
After scrubbing their presence from the web, the band returned with their literal birdsong - sung by an animated bird.
The post was shared on an Instagram account which the band appeared to have set up overnight.
They followed up on Friday with the release of the video for Daydreaming.
Radiohead registered a new company called Dawn Chorus, LLP in January, hinting that a new album was about to drop.
The band, who are the kings of the unexpected album release, did the same before releasing their two previous albums, creating a company called Xurbia Xendless Ltd. to distribute In Rainbows in 2007, and Ticker Tape Ltd. for 2011's The King of Limbs.
The alternative rock band, consisting of Yorke, Jonny and Colin Greenwood, Phil Selway and Ed O'Brien, are embarking on a busy world tour this year.
The album will drop digitally on Sunday at 7pm.
