We have been informed of the death of Roberta Knie, an American soprano who made a fine career in Europe before she was finally called to the Met in 1976.
Oklahoma born, Roberta Knie studied in London and was a member of the Vienna State Opera in the early 1970s.
She made her debut in Bayreuth as Brünnhilde in Die Walküre in 1974 and sang her first Isolde in a Wieland Wagner production in Ravenna the following year.
It became her signature role.
