Preheat oven to 375 degrees. Place bread slices on a baking sheet and bake until golden, about 10-12 minutes. Remove and let cool slightly.
While bread is baking, add goat cheese, cream cheese and roasted garlic cloves to the bowl of your food processor and blend until creamy.
Toss tomatoes with salt, pepper and olive oil.
To prep crostini, spread each slice with goat cheese then top with a handful of tomatoes, grilled corn and fresh basil. Serve!
