This is the opening poem of the Poetic Edda, chanted in a style influenced by rímur tradition by Sveinbjörn Beinteinsson, allsherjargoði (very roughly translated as "high priest") of Iceland's Ásatrúarfélagið (Æsir Faith Fellowship) from 1972-1993.
Völuspá (Prophecy of the Seeress) is one of the major sources for Norse mythology. It tells of the creation of the world, of the wars of the Norse gods, of the creation of humanity and the destruction of the world at Ragnarök (Doom of the Powers).
