Radiohead have dusted off an unreleased track written during the band's 'OK Computer' period for their new album.

Billboard reports that the song is called 'Nude' and has previously been known as 'Big Ideas (Don't Get Any)'.

According to a posting on the band's official website by frontman Thom Yorke the song will feature a string quartet.

Yorke played an acoustic version of the song in Tokyo in 1998 and it also featured in the Radiohead film 'Meeting People Is Easy'.

Radiohead's new album is expected in the summer.
