Wagner - The Ring Cycle

At four hours, this is an immersive opera. The Ring  is a cycle of four German-language epic music dramas composed by Richard Wagner. The works are based loosely on characters from the Norse sagas and the Nibelungenlied. The composer termed the cycle a "Bühnenfestspiel" (stage festival play), structured in three days preceded by a Vorabend ("preliminary evening"). It is often referred to as the Ring cycle, Wagner's Ring, or simply The Ring.
