Days Without Art Healing Walk: Greater Bostonians of all backgrounds will join artists, dancers, musicians, friends, and collaborators in a procession from City Hall to the Boston Center for the Arts’ Cyclorama. There they’ll formally open SPOKE’s 31st Annual World AIDS Day art installation and vigil, marking the effects of multiple pandemics on our lives and our communities. City Hall will be lit red in honor of those lost to HIV/AIDS from dusk Nov. 30 until dawn Dec. 1. Participants will walk from City Hall, holding small bowls that will honor the lives of our dear ones, and a 150 foot stream of red satin, evoking the AIDS Red Ribbon and the beauty of the thread of human connection.
