 Some, such as Mahalia Jackson and Bessie Griffin, were primarily soloists, while others, such as Clara Ward, Albertina Walker, The Caravans, The Davis Sisters and Dorothy Love Coates, sang in small groups.While some groups, such as The Ward Singers, employed the sort of theatrics and daring group dynamics that male quartet groups used, for the most part women gospel singers relied instead on overpowering technique and dramatic personal witness to establish themselves.Roberta Martin in Chicago stood apart from other women gospel singers in many respects.
