The Savannah Center presents "The Show Case of Music" every year.
This is an all day affair with performances in every room of the center.
Musicians change every hour and the audience is free to roam from room to room.
I don't think you get paid for the performance here as the audience attends for free.
However your performance may lead to bookings, especially from clubs for their entertainment.
Bring business cards or flyers for your contact information.
Contact the Savannah Center for more information.
