Matthew and Eleanor Friedberger aren’t concerned with making “good” music. Rather, they’re focused on doing what they do best: creating wildly experimental and imaginative music that’s as playful as it is unpredictable. And it’s just as well because this brother-sister duo are the main players in Brooklyn’s indie-rock band the Fiery Furnaces. They’ve acquired a bit of a cult following over the past six years, even drawing comparisons to the White Stripes with their first album, 2003’s Gallowsbird’s Park (Rough Trade). Now touring to promote their latest, Bitter Tea (released in the US on the Fat Possum label), the Fiery Furnaces are joined by San Francisco noise-rockers Deerhoof, who’ve been praised by the New York Times as “one of the most original rock bands to have come along in the last decade.” The tour hits Buffalo on Saturday (Oct. 28) at The Tralf, 7 pm. Multi-instumentalist and loop artist Fog opens the show.
