Found out that Clarissa Bronfman attended a NYSPCC event... looking into it. Maybe someone here recognizes guests at that event with any NXIVM connections (names listed below)

Curled up barefoot on the 1960s Brazilian sofa in the leather-swathed library, Clarissa has a laid-back demeanor that belies her formidable role in New York cultural life as a vice-chairman of Carnegie Hall, a trustee of the Museum of Modern Art, and cochairman of the Guggenheim Museum’s Latin American Committee. (She also practices photography and creates a sought-after line of jewelry.) The six-bedroom apartment, she explains, was conceived as an easygoing environment for raising four children (now ages 15 to 20) and as a flexible backdrop for the global art collection she’s assembled with her husband, a scion of the family behind Seagram distillers and the former CEO and chairman of the Warner Music Group, who is now a venture capitalist with a special interest in profitably reducing carbon emissions.
