Rachel Shukert: “It’s easy for such a list to seem like a list of the ten best Broadway musicals, period. Prince’s contribution to the American theater is so vast, so elemental, that it feels a little bit like ranking the ten best colors. A case can be made that green is a better color than yellow, but without both of them, the rainbow as we know it would cease to exist. Still, I’m always up for a challenge, particularly one that will engage and perhaps, enrage, the show-biz multiverse known as my Twitter feed.”
