Since then, the three women have been holding the Honor The Earth tour, and this year welcomes the group’s fifth one. The speaking/performance benefit outing will visit various colleges throughout the States from April 10 and wraps with a grand finale on Earth Day on the 22nd.

Each presentation will feature talks by the Indigo Girls and LaDuke, followed by a 45-minute acoustic performance by the Girls. The tour, which focuses on educating college students on environmental issues, will also visit some Native American reservations currently implementing wind power.

“When I was in college, one thing that was sorely lacking from my education was exposure to the indigenous perspective and approach to activism, specifically around cultural and environmental sustainability,” Ray said. “I don’t believe we can be activists without contemplating the effects of manifest destiny on the development of our country and its relationship to all aspects of our current movement for human and environmental dignity.

“The struggle for a sustainable and tolerant world community has always been embraced by student activists.”

Because of the artists’ personal college experience, this tour will be focused directly at college campuses – particularly those close to Native American lands, as an effort to bridge what is often an isolating gap between college students and the communities that exist very close to them.

“College campuses provide venues of dialogue where student activists are looking and working towards a clean energy future,” Saliers said. “This tour will speak to them, provide specific guidance on how to get involved, and encourage their efforts and the efforts of their neighboring Native environmentalists as they implement clean energy production such as wind power.”

Tickets are available through honorearth.org and range from $5 to $20 in price, depending if you’re a college student or just an Indigo Girls fan. All net proceeds will go to Honor The Earth’s Justice Initiative to support alternative energy in Native America.
