Portishead's Beth Gibbons has recorded a "glacial roar" for a giant polar bear that Greenpeace will use to lead a street protest in London next Sunday.
The singer recorded a roar for the double-decker bus sized polar bear puppet called Aurora, which will feature a giant sound system in its head to play the sounds of ice cracking, Arctic wildlife, and other roars donated by members of the public.
The march will be part of a global day of action to demand that the Arctic be protected from oil companies planning to drill in its waters.
