Tomorrow's Náttúra concert at Reykjavik's Laugardalur Park is an outdoor event aimed at boosting awareness of Icelandic environmental issues (specifically, "the impact of the growing aluminum smelting activity on Iceland's natural landscape," according to a press release). It's being touted as one of the largest concerts in Iceland's history, and it features some of the country's brightest musical stars: Björk, Sigur Rós, and Ölöf Arnalds.

And for a few hours tomorrow, the cause of preserving Iceland's environment will become the world's cause, as the entirety of the Náttúra proceedings will be webcasted live via National Geographic's Nat Geo Music website. The event is set to take place from 7 PM-12 AM local time, or 3-8 PM ET in the U.S. You can also buy ringtones to help support the cause.

For Björk's thoughts about the concert, go here.

After meeting up tomorrow, Björk and nudists of note Sigur Rós will part ways to tackle the rest of their respective summer tour itineraries.

One stop that Björk won't be making as planned: A July 5 appearance at Hertfordshire, England's Wild in the Country Festival. According to NME.com, a statement made on Björk's behalf says that she's pulling out "due to the volatile nature of this event. Bjork is extremely disappointed that this show will now no longer go ahead." Apparently "organisers Geoff Oakes and Vince Power for [event organizers] Renaissance have been unable to secure any staging, sound and lighting for this festival making it impossible for the headline artists to perform and are unable to fulfill their contractual obligations to all of the artists contracted to perform at their event."

Björk's people urge would-be festgoers to seek a refund, and Oakes is quoted as saying that they "hope to be able to offer refunds to as many people as possible."
