“Died Young, Stayed Pretty” is a documentary that focuses on the random people who make rock posters. Directed by Eileen Yaghoobian, the movie features talking head artists pontificating about their transient, occasionally obscene, eye-popping, promotional art. Rather than posit the poster makers as part of some as yet undiscovered movement, the film reveals how even fractured, random acts of creativity plastered across the city one day and destroyed the next expose something deeper about the unsated consumerist culture at large. Art Chantry, Methane Studios, and Stainboy Reinel make appearances as “the vivisectionists of America’s morbidly obese consumer culture.”
