The tetralogy of four operas that form Der Ring des Nibelungen (The Ring of the Nibelung) explores the conjunction of love and power in a mythic landscape in which true power resides in possession of the Ring. Composed over more than a quarter of a century, monumental in scale, and structured after the precedent of Greek drama, the cycle was first performed in 1876. Staged by the award-winning director Stefan Herheim, this innovative new production from Deutsche Oper Berlin features a leading international cast conducted by Sir Donald Runnicles.
