Chapin Sisters
Sadly, looks like the Providence show got canceled. :-( You can still see them in Boston on Friday night! If you plan to do so, and can, I seriously suggest getting tickets between the hours of 10 a.m. and 6 p.m. at the Berklee Performance Center box office at 136 Massachusetts Avenue, because the only way they sell tickets online is through Ticketmaster, and they charge a stupid markup.
