Fats Domino is missing; he lived in the now-flooded 9th Ward and had said on Monday he intended to ride the storm out at home. Irma Thomas, the Queen Of Soul, has not been heard from. Gatemouth Brown's house was destroyed, although he is apparently safe in Texas at his brother's house. The Neville family's homes have mostly been destroyed. Allen Touissant, who wrote "Lady Marmalade" and "Right Place, Wrong Time," was last heard from in the Superdome.
One can only imagine what's happening to the legions of street musicians and other not-famous artists who made New Orleans their home.
