El Sí-Da was originally staged in 1988 on the World's AIDS Day (in a time when AIDS and condoms were still taboo in Puerto Rico), this is a re-staging made in 1991 for health educators. The performance is inspired in Augusto Boal's "image theater," proposing images based on common prejudices and attitudes related to sexuality and AIDS, as a provocation to reflect and discuss new interpretations and alternatives to these social and health issues. The audience is invited to join the performers in creating and transforming images, exploring alternatives for the transformation of current social attitudes towards AIDS.
