One art world Insider called him “the most charismatic artist since Jean Michel-Basquiat.” Like the great Basquiat, Dash Snow was a graffiti writer who showed in galleries, was dismissed as a lightweight clown, became an international art star and died a drug-related death in his 20's. There's more, much more to the story of Dash Snow, an heir to a fortune who immersed himself in New York’s art world demimonde of the early 2000's. Now, Cheryl Dunn's long-in-the-making documentary begun with Snow's cooperation, “Moments Like This Never Last,” is out and destined to add to the legend of this self-destructive bad-boy artist. I talk to the director about what drew her to Snow, his impact on the art world, how the legend grew and its impact on the world.
