Radiohead frontman Thom Yorke has written a song that is 432 hours long for frequent collaborator Stanley Donwood's The Panic Office art exhibition in Sydney.
The exhibition lasts eighteen days, and the piece of music, named Subterranea, will span its entire length.
No two minutes of the work's 25,920 minutes are alike, with Australian radio station Triple J saying that it is "an eerie mix of ambient textures, experimental sounds, and field recordings", apparently similar in style to Yorke's solo album Tomorrow's Modern Boxes.
Donwood is an English artist who has designed all of Radiohead's album covers from The Bends onwards. He also collaborated with Yorke on the Dead Children Playing picture book in 2007.
There are currently no plans for the music to be released outside of the exhibition.
