In 1998, Amy Ray and Emily Saliers of the Indigo Girls initiated the Suffragette Sessions Tour, a loose amalgamation of female artists that Ray described as "a socialist experiment in rock and roll--no hierarchy, no boundaries."
The participants included Gail Ann Dorsey, Lisa Germano, Lourdes Perez, Kate Schellenbach, Jane Siberry, Jean Smith, Josephine Wiggs and Thalia Zedek.
