Boston-based singer/songwriter and rhythm guitarist Miss Tess and her combo specialize in “modern vintage” jazz, swing, and blues. They return to the Pour House behind a new two-disc live collection titled Live Across The Mason Dixon Line (recorded in Boston and Atlanta). The spiffy acoustic duo Two Man Gentlemen Band — guitarist Andy Bean and bassist Fuller Condon — share the bill armed with a new album titled Two at a Time. Local acoustic combo the Hungry Monks plays the deck at 5 p.m.
