Let this be a note to aspiring documentary filmmakers everywhere: make an environmental film about mountaintop mining and KT Tunstall will sing at your Sundance premiere party.

Okay, so I can’t really guarantee that, but for the 2011 Sundance Film Festival premiere of The Last Mountain it certainly seems to be the case.

The documentary film focuses on the practice of mountaintop mining in West Virginia’s Coal River Valley, and shows how residents and activists have begun to stand up to the industry that is devastating their region. In addition, the film features Robert F. Kennedy, Jr. and all proceeds from ticket sales will go to benefit the global environmental organization that he started in 1999, Waterkeeper Alliance.

Last night the film premiered at Sundance, and the ensuing party held at 3opolis/3D Lounge at The Yard in Park City, UT featured performances from Grammy Award nominee Tunstall, and was hosted by Robert F. Kennedy, Jr. and Harry Belafonte.

The Salt Lake Film Center founder and director Geralyn Dreyfous, said that last December Tunstall performed at a benefit concert for the Waterkeeper Alliance, and that, “KT fell in love with the area and the work of Waterkeeper.” She then continued, “She asked if I could introduce her to people in the independent-film world, and I told her to come out to Sundance. She agreed to come back to do a benefit and is donating her time.”

And in terms of Belafonte’s involvement in addressing the party attendees about the importance of activism, “Harry’s daughter lives in West Virginia,” Dreyfous stated. “Her son-in-law is in charge of the United Mine Worker’s Union, who have been fighting for miner’s rights in the area. So this is a personal cause for Harry.”

Did anyone who went to Sundance get a chance to check out The Last Mountain??
