THE RADIATORS : “Zig-Zaggin’ Through Ghostland.” Epic **: <i> Albums are rated on a scale of one star (poor) to five stars (a classic).</i>

New Orleans’ second-favorite (to the Neville Brothers) sons attempt to spice up the commercial ingredient in their white-soul/bar-band/blues gumbo, with less-than-finger-lickin’ results most of the time. Instead of moving toward the elegant, contemporary blues of a Robert Cray or the fiery blues-rock of a Mason Ruffner, the Radiators land facelessly smack dab in the middle of mainstream rock. On the title tune the band locks into an infectious, rolling rhythm worthy of a Crescent City street parade, and they turn in a solid version of J.J. Jackson’s 1966 hit “But It’s Alright.” The rest of the time the Radiators sound more like a band you’d find in a Red Onion than Tipitina’s. They’ll be at the Coach House on Wednesday, the Palace on Friday and the Ventura Theatre on Saturday.
