Our aim is to bring the performing arts to communities who do not have easy access (including rural, disadvantaged communities, the elderly), to provide a platform for young, upcoming performing artists and to promote South African composers.
We support creative collaboration that contribute towards the United Nations SDG goals and therefore collaborate on interdisciplinary projects with other institutions and organizations. As a non-profit company The Rainbow Exchange NPC relies on the support of the public, funders and donors to reach our goals and objectives.
