With the theme “More Lights, More Love,” Light City Baltimore will expand from two to three weekends this year. The art and music festival presented by the Baltimore Office of Promotion and the Arts (BOPA) is held primarily on Baltimore’s waterfront and highlights social innovation by way of the arts—large-scale art installations that light up the evenings, alongside live music and pop-up performances.

“This is a unique festival in the sense that the art is supposed to elucidate and illuminate social issues,” says Verna Myers, representing the Light City leadership council at a press conference today. “Art is awesome because it helps us to see things differently.”

The three-part event kicks off with Neighborhood Lights from April 6-8, continues with the Light City art and music festival from April 14-21, and concludes with [email protected] from April 18-21.

Perhaps the most obvious signal that the event is in full swing will be the BGE Light Art Walk along the Inner Harbor’s promenade, showcasing 21 light-based installations made by artists from across the world. Tom Dekyvere’s glowing Elantica will be an off-the-grid sculpture replica of Earth, made from solar panels and electronic waste. Another piece will explore human relationships by way of interactive light and sound. Another will serve to illustrate—through a moving, patterned surface on the ground—that color is made up in our minds.
