The French Björk fan-site, bjork.fr, has let us know that the Icelandic singer and Radiohead frontman Thom Yorke will release the result of a second team effort via Björk label One Little Indian on October 20. The single, ‘Nattura’, is recorded in support of Icelandic environmental organization Nattura.

Björk and Yorke has previously worked together on the duet ‘I’ve Seen It All’ from the soundtrack to Lars von Trier’s movie Dancer In The Dark (2000), and earlier this year Björk and Sigur Rós did a support concert for Nattura in Reykjavik.
