This Friday, Aug. 16, is the 25th anniversary of Elvis Presley's death, and University of Colorado at Boulder art historian and author Erika Doss is documenting what the date means in American society. In 1999, Doss wrote "Elvis Culture - Fans, Faith, & Image," an examination of Presley's enduring presence in popular culture. The book takes a hard look at how the performer's image is related to sex, religion and racism in the lives of his fans.
