Kalevala The Musical is a story of ancient legends, told by the spirits of the haunted forest of Kalevala, that is adapted from the national epic poem of Finland. Passed down from generation to generation, these tales were finally collected in a book of poems by Elias Lonnrot in 1835. Widely cherished across the world. Since then Kalevala has been a source of inspiration to many fantasy authors, including J.R.R. Tolkien.
