Martha Friend, local curator and collector of all things blue, fell in love with the color early on in her life. As a result she’s spent years building “Sapphire City,” an art installation outside her home on Highland Avenue in Somerville, which many in the area would recognize as an unofficial community landmark. Her work has garnered media attention and her vision for this exhibition is translated through artworks by local artists, installations of found objects, music, and creative workshops. Friend invites visitors to explore the many different meanings and uses of blue and leave with a newfound appreciation for the color’s history and influence on art and culture.
