The best murals of 2015 were created by a cool assortment of local, national, and international artists — including Berlin-based Karl Addison, Hong Kong-based Cara To (
aka Caratoes), Los-Angeles based Miles "Mac" McGregor (
aka El Mac), and Tennessee-based Rebecca Green. Some painted alone, and others were part of collaborative projects. The Colibri Center for Human Rights in Tucson engaged several renowned muralists to create a migration-theme mural on the La Melgosa building in the Grand Avenue Arts District. Other locations for this year's best new murals include Roosevelt Row and Calle 16.
