“How can we continue to allow oil money to dictate our environmental and social policies?” Matthews, a Seattle resident, posted on his Tumblr page. 

UPDATE: Dave Matthews and Tim  Reynolds played to a sold out crowd last night wiht several guests. Watch a recording of the concert below.

Dave and Tim's set starts at the 2 hour, 35 minute mark.

ORIGINAL TEXT: The Dave Matthews Band announced a concert where all net proceeds "will be utilized to support the Standing Rock Sioux Tribe in its opposition to the Dakota Access Pipeline."

The concert is scheduled for November 27 at the Daughters of the American Revolution Constitution Hall in Washington D.C., a 1929-built National Historic Landmark seats roughly 3,700 people.

“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,” the band wrote on its website.

Additional show guests are expected.

"How can we continue to allow oil money to dictate our environmental and social policies?" Matthews, a Seattle resident, posted on his Tumblr page. "The people of Standing Rock, and people standing with them, are standing up for their children.  They're standing up for all of our children.

“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.  Oil is not safe.  If we let this happen, we should be ashamed of our country.”

The online ticket presale started for DMB fan club members, and tickets for the general public go on sale Friday at 10 a.m. Eastern.

Protests in North Dakota

Hundreds of people have been protesting in southern North Dakota for months, supporting the Standing Rock Sioux tribe's opposition to the $3.8 billion pipeline from North Dakota to Illinois. Officers from several states have been helping North Dakota authorities with the response.

Protesters at the demonstration against the Dakota Access pipeline are increasingly divided over how to stop the project, with militant younger activists seeking more aggressive tactics and an older crowd arguing for peaceful protest centered on prayer.

The differences came to a head last week after law enforcement officers in riot gear forced hundreds of protesters off an encampment on private property. In response, some demonstrators torched three vehicles on a bridge, creating a blockade that effectively cut off easy access to the pipeline construction zone and made it far harder for the Standing Rock Sioux tribe and nearby residents to get to Bismarck for errands and medical appointments.

Many other protesters insist that their cause cannot resort to law breaking, and they support the threat of eviction that the main camp has issued against people who would cause problems.

"We don't want people instigating things that are going to get out of hand. We don't need them," said Don Cuny, chief of security for the large camp near the confluence of the Missouri and Cannonball rivers.

With the potential for more violence, tribal elders have asked that children be removed from the camp.

"They want the kids out of here if things get ugly," said Emmett White Temple, a 55-year-old member of the Standing Rock Sioux.

A Denver woman was charged Monday with attempted murder by authorities who said she fired three shots at law officers during Thursday's operation.

The sprawling encampment known as Oceti Sakowin, or Seven Council Fires camp, is on Army Corps of Engineers land. Within it are smaller camps occupied by protesters from across the U.S. and beyond. Residents are hesitant about singling out the group or groups that set the vehicles on fire, but they overwhelmingly point to a young crowd of campers.

For months now, opponents of the four-state, $3.8 billion pipeline have been camping in this area about 50 miles south of Bismarck. They worry the pipeline will disturb cultural artifacts and threaten drinking water sources on the Standing Rock Sioux's nearby reservation and downstream.

The pipeline's operator, Texas-based Energy Transfer Partners, insists the project is safe. The tribe is fighting the pipeline's permitting process in federal court.
