Yggdrasil is a new record by the Norwegian women’s choir Cantus conducted by Tove Ramlo-Ystad. There are eleven works on the record by various composers and all inspired, more or less loosely. by the idea of the World Ash Tree of Norse legend. Sometimes they are a fairly literal telling of some episode from myth, other times they explore broader ideas around a tree that lasts for a long time, but not for ever, and contains within it its own destruction and the seed of its rebirth. So, themes of humanity and Earth’s place in the Cosmos, the destructiveness of war, greed and climate change all have their place.
