The festival tradition is a proud one in Louisiana, with a festival dedicated to almost every manner of seafood, vegetable and style of music. The Gretna Heritage Festival has the usual assortment of games, rides, crafts and food, and it offers one of the most ambitious and diverse musical lineups on the festival circuit. Cover bands the Chee-Weez and the Topcats perform this year, as does Cajun fiddler Amanda Shaw and Rosie Ledet & the Zydeco Playboys. On an even more local front, the Iguanas (pictured) have relocated to Austin for the foreseeable future. That won't hinder first return date (Saturday) in the New Orleans area since the hurricane. New Orleans' R&B tradition will be represented Friday night by Clarence "Frogman" Henry. The festival distinguishes itself by mining the 1960s and '70s for acts, and this year's lineup includes Chuck Negron of Three Dog Night fronting Blood, Sweat and Tears, and Dennis Edwards -- David Ruffins' replacement in the Temptations -- leading the Temptations Review. On Saturday night, Edgar Winter of "Frankenstein" fame performs, followed by the thinking man's metal of Blue Oyster Cult. BOC is still fronted by the three-guitar lineup of Buck Dharma, Eric Bloom and Allen Lanier, and rather than just play the hits, they continue to explore their back catalogue. "Godzilla" and "Don't Fear the Reaper" are staples of their set, but it's not uncommon to hear "Transmaniacon MC" or "Then Came the Last Days of May," too. Admission $5 daily, $10 all-day pass, $20 all-weekend pass.
