Toundra, a four piece post-rock outfit from Madrid, are gearing up for the release of their fourth album, numerically and pleasingly titled IV. The album is available exclusively to stream below via The Independent. IV tells the story of two foxes that need to escape from the forest where they live as a huge fire ravages their home. This story serves as a metaphor for humanity destroying the environment and ties in with the artwork and videos, evoking a strong sense of the concept despite the music being entirely instrumental.
