My very first concert about 12 years ago was the Celine Dion concert at the peak of her career. She chose to perform “in the round” so that she could feel the energy from the crowd from all different sides. As an attendee, I also felt the amazing energy that came from this set up.
This style of seating that is away from the traditional theater set up has made its way to the wedding industry as well. I love when ceremonies are performed in the round. Guests are closer to the couple and there will not be a bad seat in the house. It is also symbolic in that you start your married life in an unbroken circle.
