Mayor Ray Nagin isn't out of office but he's helping out with his next recovery project. The City of New Orleans co-sponsors a performance by Los Hombres Calientes, featuring Irvin Mayfield and Bill Summers, to benefit Haitian earthquake victims. The benefit is at 8 p.m. Tue., Feb. 23 at the House of Blues (225 Decatur St., 310-4999). Proceeds go to the Red Cross Haitian relief efforts.
