Billie Eilish is the most interesting voice working in popular music today. Unequivocally. Inescapably.  She is that rarest of all possible stars in that she is at once immensely populist and intensely insular in her songcraft.  Yes, she does write the hits – pulling into her voice everything from ASMR whispers to sound poetry — but they are hits that are so intimate that you can look out upon any of her audiences and watch them imbue those hits with their own deeply personal meaning in real time. Tonight she joins Scott Goldman and her producer / singer brother Finneas in conversation about private life, her new video for “all the good girls go to hell,” her September 28 debut on Saturday Night Live, and the creative impulses that have sculpted this singular voice into the work of art spazzing before you tonight.

Billie Eilish and Finneas play at 7:30 p.m. on Tuesday, September 17 at the Grammy Museum.
