Ailing

Soprano Deborah Voigt was ill with a stomach flu last night, and her understudy, Erin Wood, made her San Francisco Opera debut as Amelia in Un Ballo in Maschera. Wood's voice is cold and pretty, but not nearly as expansive as Voigt's. At times she was slightly shrill and had too much vibrato. Wood wore a purple gown instead of the gold one worn by Voigt in the last scene.
