Kathryn Calder is a member of Immaculate Machine and The New Pornographers. She plays keyboard and sings in both bands. Many of the parts she sings live with The New Pornographers are as a replacement for Neko Case (Neko still occasionally returns); however, Calder has been given an increasingly large role with the band. She is the niece of New Pornographers leader Carl Newman. Wikipedia
