Experimental rock giants Radiohead are working on a new album -- or at least it would appear so from the cryptic messages of frontman Thom Yorke.
In what online fans widely interpreted to be a tease, Yorke has in recent days made a series of suggestive tweets including a link to an untitled picture of a white turntable in between his calls for the world to fight climate change.
In his most explicit message, Yorke said that he and Stanley -- presumably longtime friend Stanley Donwood, who has designed Radiohead's cover art -- were "going through 15 years of discarded words and pictures."
Yorke said that Radiohead has done "overdubs" in its studio but that the British rockers were in their "second day only."
The hints would confirm a statement earlier this year by Radiohead lead guitarist Jonny Greenwood, who told the BBC that the band would start recording a new album in September.
The album would be Radiohead's first since 2011's "The King of Limbs," an experimental work in both music and marketing with Radiohead selling it digitally from their website without a record label.
Radiohead quickly won a following with its 1993 debut album "Pablo Honey," a work of guitar-driven alternative rock that featured the song "Creep." The band soon took a more original and electronic turn through its seminal 1997 album "OK Computer."
