Sisterz of the Underground (SOTU) is a community, network, and support system created by, and for, females who choose Hip-Hop as a form of expression. As an open Hip-Hop collective, SOTU aims to encourage the integration of different elements of Hip-Hop, use the elements as tools for education and social change, as well as provide opportunities to showcase the elements -- such as the annual Sisterz of the Underground event.
