Two of Iceland’s greatest exports are teaming up on Saturday for a concert webcast. National Geographic Music (huh, wha?) is responsible for this double-team of awesomeness. The concert begins at 7 p.m. GMT, which means that’s like 3 p.m. Eastern or 12 a.m. Pacific. (Someone correct me in the comments since I’ve never been good with time zones).

If you miss it, there will be an on demand stream of this on the website or will probably show up on YouTube.

The Náttúra concert will be an open-air event, held at the Botanical Garden on Laugavegur, near the center of Reykjavik, Iceland. The country boasts the largest unspoilt wilderness left in Europe, and Náttúra is being organized as a response to the ongoing environmental degradation caused by Iceland’s increasingly invasive aluminium smelting activity.

“Too often battles being fought for nature turn into something negative and into mudslinging,” Björk said in a recent press statement. “We will not go that way, we are not saying that this and that is forbidden, we are rather asking ‘what about all these other possibilities?’ The 21st century is not going to be another oil century but rather a century where we need to recycle, think green and design both power plants and our surroundings in harmony with nature.”

The Náttúra concert will also spotlight the book Dreamland: A Self-Help Manual to a Frightened Nation by Andri Snær Magnason. The book, a best-seller in Iceland, is published in English next month by Citizen Press and has already won the Icelandic Literary Award and the Icelandic Bookseller Prize.

If Sigur Ros’s new material and recent concert performances are any indication (best band in the world?), it might be worth it to sit inside or on a porch with a spliff or a brew and watch this arty-environmental shindig.
