Iconic performer Dave Matthews has been tapped to host a concert at DAR Constitution Hall in Washington, D.C. on Sunday, November 27 dubbed “Stand With Standing Rock.” Additional artists are expected to be announced soon with all net proceeds from the show to be utilized to support the Standing Rock Sioux Tribe in its opposition to the Dakota Access Pipeline.

“How can we continue to allow oil money to dictate our environmental and social policies? The people of Standing Rock, and those who are supporting them, are standing up for their children and all of our children,” said Dave Matthews. “We are letting the Dakota pipeline silence their voices. Not only are they desecrating sacred lands, but they also threaten to poison the Missouri River.”

Here’s more info about the concert:

The funds raised will help provide supplies, legal assistance and other necessities to the “water protectors” – the protesters who are currently at the frontlines of the tribe’s fight. Hundreds of water protectors have occupied an area adjacent to the pipeline’s path since April. The pipeline will cut through land that belongs to the tribe based on the terms of a 19th century treaty and will go under the Missouri River, threatening the Reservation’s water source. Following the concert, grassroots efforts will take place throughout the day in Washington, DC on Monday, November 28.
