If incessant nitpicking and network blatherskite are ruining your election night, this lineup might ease your bleary red, white and blue eyes: Murder By Death, J. Roddy Walston & The Business and William Elliott Whitmore play Uncle Pleasants (2126 S. Preston St., 634-4147) Election Night. Whitmore’s new album on Anti drops next year, and you will most likely get a taste of it Tuesday. Murder By Death, featuring hometown gal Sarah Balliet, will weave its cabaret-like miasma, and the soon-to-be-hitched J. Roddy Walston & The Business is heir apparent to the title of “America’s Bar Band.”
