If you happen to be in Iceland today you might want to head on over to the Botanical Garden on Laugavegur, near the center of Reykjavik, where Björk and Sigur Rós will team up to perform a free concert. The Náttúra concert is a bid to raise awareness of the destruction of Iceland's natural landscape from aluminum smelting.

If you can't be at the concert, National Geographic World Music will be webcasting the concert live from from 7pm to 12pm GMT (3pm—8pm EST).
