Sigur Rós have released a new edit of their soaring hit "Hoppípolla"

The original version of "Hoppípolla" arrived on 2005's Takk... and has been a firm favourite for the BBC since its release, most notably featuring on the first Planet Earth's trailer in '06.

Now a new version has arrived for the show's second instalment, with the band also delivering a statement about the environment:

"In Iceland we are blessed with a seemingly inexhaustible supply of wild and untamed places. But even here, in the very furthest flung corners of Europe’s largest wilderness, the scars of human industry are visible, the plans for future encroachments, by dam and smelter, legion. If lost the Icelandic highlands are not recoverable. Around the world the story is the same; the traffic, literally, going in one direction. Sigur Rós are proud to be associated with Planet Earth II and its all-important mission to hold us rapt in understanding of, and respect for, this endlessly fascinating, utterly surprising and ultimately fragile place we are lucky enough to call home for a short while."

In related news, Sigur Rós frontman Jonsí was recently said to be working with pop master Ryan Tedder on solo material.
