Add Product Categories Tutorial
These are the steps to add product categories. You will want to create a Parent Category titled after the Show, and all the Artists will go under that Category.
1. On the WordPress Dashboard, click “Categories” under the Products menu.

2. Set the name of the Category.
If you are creating the Show category, you only need to enter the name and make sure “Parent category” is none.
If you are creating an Artist category for a show, only enter the Name and make the “Parent category” is set to the correct show.
When done, click “Add new category”

3. Once the Parent category and all the Artist categories are added, they will be available for you to choose when adding products!
