The threat of Hurricane Ivan has forced Louisiana promoters to postpone or cancel several concerts scheduled for the coming days. At the top of the list is Tim McGraw's annual Swampstock event, which was set for Sunday (Sept. 19) in Rayville, La., about five hours northwest of New Orleans.

"I regret that we have to postpone the show this year but it's the right thing to do with the weather that's headed that way," McGraw says. "My thoughts and prayers are with people of Louisiana as they prepare for the storm."

As previously reported, the celebrity softball and concert event was due to feature McGraw and his wife, Faith Hill, as well as Martina McBride, Jeff Bates, Big & Rich and the Warren Brothers, with proceeds to benefit area charities.

A rescheduled date will not be considered until after Hurricane Ivan passes and its impact on the region is assessed.

As hundreds of thousands stream out of the southernmost reaches of the state, House of Blues has officially canceled several concerts at its New Orleans venue. Affected is tonight's (Sept. 15) My Morning Jacket/Willy Mason/Centromatic show and tomorrow's Toots & the Maytals/Ricky Fante and Antibalas Afrobeat Orchestra gig.
