Hi Kired.  Nice that you are the ‘contributor’ here and and not some stranger – welcome. 
Probably lots of people  are thinking the same as this: 
“Grace Potter and the Nocturnals have something so exceptional and flat-out hot that we, unfortunately, may never see them on Nantucket again. If they do decide to keep coming back to our special island, I doubt we will get to see them for twenty bucks. And that, quite simply, is the deal.”
 I had the feeling last fall at Revolution Hall that they might have outgrown that venue, and was so disappointed they had to cancel there this spring – feel fortunate to have seen them even once in such an intimate setting, though.
