O’Bannon (Farscape) and starring Grant Bowler, Julie Benz, Stephanie Leonidas, Jaime Murray, Tony Curran, Graham Greene, Mia Kirshner and Fionnula Flanagan. Bear McCreary (Battlestar Galactica, The Walking Dead) is composing the show’s score. It has been announced this past week that the composer’s new label Sparks & Shadows will release a soundtrack album later this year.
