Bennett originally trained as an actor at the Lee Strasberg Theatre and Film Institute in New York. Bennett then became an alumnus of the Berklee College of Music in Boston. Beginning in the mid-2000s, she began to appear as an opening act, or as a guest during, her father's shows. In 2013 she was married to Ronen Helmann, an Israeli; around the same time, she converted to Judaism.
In 2002, The New York Times ' Stephen Holden compared Bennett's voice to that of Billie Holiday, Rickie Lee Jones, and even Betty Boop. A JazzTimes profile from 2010 said that her voice does not resemble that of her father's, and instead compared her to Jane Monheit and Nellie McKay.
Bennett's debut album Embrace Me, a treatment of standards from the Great American Songbook, was released on Perseverance Records in 2014. It followed the release of EP in 2010 called Natural and a digital-only album in 2012.
