Radiohead frontman Thom Yorke has written a song which is 18 days long.
The British rocker put together the innovative music piece, which stretches over 432 hours, for an art exhibition by Stanley Donwood, who has created all the band's album covers since 1994.
The song, titled Subterranea, is the soundtrack to Donwood's The Panic Office show, which is currently on display in Sydney and features Radiohead's cover art and band posters.
Yorke reportedly has no plans to release the track after the exhibition closes next month.
