“All three Rhinemaidens projected vividly, with Harriet Williams as Flosshilde in particularly luscious and buttery mezzo voice.”

“Harriet Williams (Hannah) is the find of the season: a polished mezzo with natural authority.”

“Harriet Willams moves, as she sings, with unfailing rightness, her French impeccable.”

“The singer I would hurry to hear more of was the touching Fenena, Harriet Williams: there is a rich quality to this attractively formed voice that bodes well.”
