Restless sonic chameleons the Fiery Furnaces revolve around the brother and sister duo of Matthew and Eleanor Friedberger, whose prickly childhood relationship and musical family set the stage for their playful, unpredictable music. The Friedbergers' grandmother was a musician and choir director at a Greek Orthodox church near the family's home in Oak Park, IL; their mother, who had a penchant for Gilbert & Sullivan, played piano and guitar and sang; and throughout school, Matthew played standup bass. While the Friedbergers weren't the closest of siblings growing up, after college and separate trips abroad they returned to Oak Park and began working on music together. The pair mixed simple, poppy melodies with a dizzying array of wordplay, sounds, and influences, including the Who, Captain Beefheart, Os Mutantes; dashes of folk, blues, and garage rock; and Eleanor's adventures in Europe. In 2000, they moved to Brooklyn, took day jobs, and began playing as the Fiery Furnaces late in the year.
