Music legend Stevie Wonder is among the artists who will perform at a concert in New Orleans to mark one year since Hurricane Katrina devastated the Gulf coast of the US.
Other artists due to perform at the concert on Tuesday include blues singer Dr John, Grammy-winning gospel performer Yolanda Adams and keyboardist Ivan Neville.
Musician Ivan Neville, whose family was displaced by Katrina, has called the concert "one small step" towards helping people recover from the devastation of the hurricane.
Money raised from the show will help rebuild the cultural infrastructure of the Louisiana city.
A film about the hurricane, narrated by Meryl Streep, is also opening.
