Newton artist Roberto Mighty presents a public, new-media, fine art project, Trees of My City, in the Hunnewell Building Lecture Hall of the Arnold Arboretum. His work focuses on dormant, dead, and decaying trees in surprising and beautiful ways. While photography is the main component of the Arboretum exhibition, the reception will also feature high-definition video and audio surround-sound installation. There will also be an on-line component using geotagged locations of the subjects portrayed in the show. Opening reception from 1 – 3 on Saturday, January 22. Show will remain on display through March 6. For more information, log on to www.arboretum.harvard.edu/news-events/art-shows/.
