This Friday, Aug. 16, is the 25th anniversary of Elvis Presley's death, and University of ÃÛÌÇÖ±²¥ 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.
