Several years ago, we visited artist David Sena‘s studio to peep behind the curtain and find out about his unique process. Sena (who has given a few CH staff members tattoos in the past) creates large-scale artworks using an unusual method: the Cooper Union graduate “paints” almost exclusively using fireworks. The results are fantastic. The artist translates rough burn marks and leftover trails from smoke bombs into mesmerizing pieces that viewers would never believe were born from roadside explosives. We donned respirators and went back to visit Sena—and finally capture his work on film.
