Tomorrow (Saturday, June 28th) at 3pm EST, National Geographic Music will be streaming a live concert from Reykjavik featuring hometown favorites Sigur Rós and Björk. The free show is a benefit to raise the awareness of the impact that the growing aluminum smelting is having on Iceland’s environment.

While Sigur Rós is not a political band by any means, they are no strangers to environemental causes that affect Iceland.

Also, if you haven’t checked out their latest masterpiece Með suð í eyrum við spilum endalaust, you are missing one of the year’s best albums.
