Pour boiling water over the sun-dried tomatoes in a heat-resistant bowl to hydrate. Let stand for 2 minutes; drain. Combine the sun-dried tomatoes, olives, capers, olive oil and garlic in a blender or food processor container. Process until blended.
Arrange the bread slices in a single layer on a baking sheet. Bake at 400 degrees for 8 to 10 minutes or until golden brown. Spread the cream cheese on the bread slices. Top with the tomato mixture and sprinkle with the basil. Arrange the crostini on a serving platter. Do not assemble the crostini until just before serving.
