Siegfried is the third of the four operas that constitute The Ring of the Nibelung, by Richard Wagner. It premiered at the Bayreuth Festspielhaus on August 16, 1876, as part of the first complete performance of The Ring. Wagner recountes The Story of the Youth Who Went Forth to Learn What Fear Was, based on a fairy-tale of the Brothers Grimm. It concerns a boy so stupid he had never learned to be afraid. Wagner wrote that the boy and Siegfried are the same character. The boy is taught to fear by his wife, and Siegfried learns it when he discovers the sleeping Brünnhilde. This 1963 recording stars Wolfgang Windgassen and Hans Hotter. Sir Georg Solti conducts the Vienna Philharmonic.
