There are high barriers to entry that keep young people from establishing their own credibility in broadcast initiatives, informed by perceptions of legitimacy, authority, and expertise. These ageist undertones reinforce a system of social and cultural beliefs that devalue the voices and perspectives of young people and, particularly, of young women. In response, Sienna has designed and launched undercurrents, a radio-magazine aired on Barnard Colleges broadcast, WBAR, which seeks to explore barriers to social justice through activist interviews and artful resistance. It features a variety of contributors and utilizes an array of formats. By including dialogue with students and experts, caller feedback, musical tracks, and news sound bites all centered on a monthly theme, undercurrents makes for an informative and engaging segment that seeks to promote the cultural and creative welfare of the community.
