Some evacuees who survived Hurricane Katrina and ended up in Colorado were treated to a special benefit concert Monday night at Red Rocks Amphitheatre.The sold-out, five-hour show by the Dave Matthews Band and the Neville Brothers raised more than $1.25 million for Hurricane Katrina victims.The Dave Matthews Band had already performed three concerts at Red Rocks and offered to stay an extra night if the city of Denver would coordinate the fundraiser. The Neville Brothers, who are all from New Orleans, also came to play.Matthews told the crowd of about 9,500, "This is just part of an effort I think on the part of everybody in the country to rebuild one of the cultural centers of the world to its former grandeur."Aaron Neville, who closed his band's set with an emotional version of "Amazing Grace," has said he believes much of his home is under water and he hasn't heard from many of his friends. He and his brothers are donating a portion of their record sales toward the relief effort, and they have appeared in several other charity shows in the past two weeks.All of the money raised during the evening, from the ticket sales to the food concessions and parking, was donated to the hurricane recovery effort.Tickets ranged from $58.50 to $1,000. Denver Mayor John Hickenlooper told the crowd it was the "most completely donated show in history."The city, which owns Red Rocks, waived the seat tax and rent. Dozens of workers, from police, firefighters and paramedics to stagehands, concession stand workers and parking lot attendants, donated their time. First Data Corp. bought tickets for hurricane evacuees staying at Lowry Air Force Base in Denver.
