Kathy Mar worked as a professional folksinger and streetsinger in Denver for many years before she discovered filk and filkers discovered her. Her first recordings were for Off-Centaur Productions (Songbird, On a Bright Wind, Bamboo Wind) and she went on to do two albums with Thor Records (Plus Ca Change, Plus C'est Les Meme Chose) which have recently been re-released as a CD double. She also did an album for Dandelion Digital (Made by Magic) with British songwriter Zander Nyrond which was one of the first filk CDs ever produced. Her cover album of her favorite filk and folk songs on Prometheus (My Favorite Sings) has been her most successful to date. She was inducted into the Filk Hall of Fame in only the second year of its existence and, with Lindy Sears, instigated the Dandelion Conspiracy to promote filk to general SF conventions.
Kathy lives in San Leandro, CA in a commune and is the mother of Michael (1970-1982), Melanie (1972) and twins Nicolas and Cassandra (1985). Her primary life partner Dean Dierschow (familiar as her most devoted roadie) lives there with her in a wonderful ongoing courtship. She was very involved in the antiwar movement in the sixties and sang in Kansas City for the first Moratorium. She has appeared as filk GOH at almost every filk convention and many regular SF conventions as well.
