Her name is Kathryn Calder, and she's Canadian; ergo she's a member of one of their super groups (in this case, it's New Pornographers). She is Michael Des Barres to Neko Case's Robert Palmer (when Power Station toured, Palmer did not and Michael Des Barres tried to fill his shoes).
Later Des Barres played in 11 episodes of Melrose Place, so perhaps a similar future awaits Kathryn Calder. Perhaps Grey's Anatomy or Desperate Housewives.
