Rockerbuilt primarily is a design-and-build shop with highly skilled metalworkers, woodworkers and, well… makers of just about all things. Its name comes from the common ground of its founders — music. With its latest location, in Portland, the shop decided to include a 3,000-square-foot gallery and live performance space. The opening features art by Craig Bunting and Michael Brinkerhoff and live music by Zim Marim, performing neo-traditional Zimbabwean marimba music and South African Jazz. The show runs through Oct. 28.
