Concrete Vocal Band performed to a wedding ceremony I organized last week (August 15th, 2017). As an Event/Wedding Planner I meet a lot of performers and vendors all the time. And I can tell that this a capella group is just AMAZING! I was already delighted by the videos I watched before hiring them but listening to them in real is something else. They are incredible singers, really professional, on time and so accommodating! They added two songs that were not even in their repertoire to please the couple who had specific requests. And it was a huge success!
