But he is most nervous when his wife, Marta is directing a new production, as she did opening night of La Traviata for the Los Angeles Opera. But there was no need for him to be concerned, because Marta scored a perfect 20 in this visually stunning production, featuring soprano Elizabeth Furtal as the beautiful and doomed Violetta.
