How would you describe this on a CV?

I'm in the process of updating my photography curriculum vitae, and I'm not sure how to mark one of the exhibitions. Typically they are either a group show or a solo show, but there is one I participated in a few years ago where each artist involved was given their own space to do whatever they wanted with. The event was like a group showing of solo shows. The only theme between any of the artists was that we all worked in the same region.

How should I identify this one. Group? Solo? Something else?
