In a large saucepan, cook bacon over medium heat until crisp. Cook bacon, and let drain on paper towels, reserving one tablespoon drippings in a pan.
Add butter to pan; stir in shallot and garlic, and cook until tender. Add wine, and cook until wine evaporates. Add cream and bring to a simmer. Add brie, cream cheese, and parmesan, stirring until melted and combined. Stir in Slap Ya Mama Original Blend Cajun Seasoning. Cover and refrigerate until cold.
Preheat oven to 450°. Pour rock salt onto a rimmed baking sheet.
Arrange oysters on prepared pan. Top each oyster with about 2 tablespoons of brie sauce and 2 tablespoons bread crumbs.
Bake until browned and bubbly, 10 to 15 minutes. Crumble reserved bacon, and sprinkle over oysters.
