For the past couple of summers, the Cleveland Museum of Art has hosted Ohio City Stages, a weekly summer block party that takes place in front of the Transformer Station throughout the month of July. Mokoomba, a Zimbabwe band that blends traditional Tonga and Luvale rhythms with funk, ska and soukous, will perform tonight at 7:30, and admission is free. Vendors will be on hand to sell food and drink as well. In addition, Studio Go, the CMA's mobile art studio, will offer hands-on art-making activities, pop-up drawing classes and other family-oriented art projects. (Niesel)
