From Dana Rose Falcone’s article for Entertainment Weekly:
Whether you livestreamed the acts or experienced them live in Grant Park, chances are you’ll love the images photographer Jill Greenberg captured behind the scenes from the fest. Featuring stills of artists like Alesso, Tove Lo, and Charli XCX, Greenberg’s photos were taken for Instagram’s Portrait Series.
“I had about three to five minutes for each artist or band, so it was simpler when it was just one singer to get a nice portrait,” Greenberg tells EW via email. “I was working alone with no lights or reflectors and a DSLR. In most cases I had not heard their music so it was a bit crazy!”
