It is important to note that:
* The name "Amici" is commonly used for Italian television shows. Therefore, there might be a different concert title you are referring to.
* There are many concerts held every year. Without a more specific title or context, it's difficult to identify this particular event.
Please provide more information about the concert, such as:
* The full name of the concert
* The location of the concert
* Any other details you know about the concert
With more information, I might be able to help you identify the actors and actresses who appeared.
