NEW ORLEANS (AP) — With prayer and the somber ringing of church bells and the uplifting sounds of brass bands and music, residents across Mississippi and Louisiana Saturday will pay homage to those who died in Hurricane Katrina, thank those who came to rebuild and celebrate how far the region has come from that devastating day when the hurricane struck. The neighborhood was one of the bastions of black homeownership in America when water burst through floodwalls on one side, pushing houses passed down through generations off foundations and trapped residents on rooftops pleading for help from passing helicopters. In addition to the former president the event will feature performances by the city's "Rebirth Brass Band," award-winning journalist Soledad O'Brien and Chief Monk Boudreaux and the Wild Magnolias.
