 They started out as a college band in Vermont before being called the rightful heirs to the Grateful Dead in terms of being a massive jam band. And now, given their shows at the Sphere in Las Vegas and 13 shows in a row at Madison Square Garden and full weekend festivals where they are the only act playing, in some ways now they're bigger than ever. And that's because the relationship between Phish and their audience is tight. I should know.
