Canadian soprano Edith Wiens has a lighter and thinner voice than many soprano soloists, and uses the French style of vibrato in which the pitch remains constant. The effect is emotionally compelling in Dona Nobis Pacem, in much the same way that the first soloist to sing this work, Renee Flynn, was.
