The Women's March made a huge impact, in part because of its widely worn pink knitted "pussyhat." Does the March for Science need its own unifying symbol? Lighting designer Steve Lieberman is "the man behind the lights" for the country's leading electronic music festivals and nightclubs. He talks about his early experiences with rave culture, and what it takes to spark the excitement of today's EDM fans.
