When she first joined the New York Philharmonic Orchestra back in 1966, Orin O’Brien had to get changed in the toilets because there was no women’s dressing room.

She might not have made it at all if it were not for the support of Leonard Bernstein. Her attraction to playing in that context stemmed partly from her preference for being in the background, working together with other musicians to create something bigger, so she was not a natural trailblazer. Together with her niece Molly O’Brien, who directed this Oscar-shortlisted short documentary, she looks back through press clippings from the time. Many words are spent describing her clothes, her looks, her imagined love life and domestic ambitions – and, of course, comparing her curves with those of her double bass.
