Baiman grew up in Chicago, Illinois. She has described her father as a "radical economist" and her mother is a social worker. When she was young, her parents took her to meetings at the Ethical Humanist Society of Greater Chicago. After becoming an Illinois State Fiddle champion at age 17, she moved to Nashville to pursue music.
Baiman is the co-founder of Folk Fights Back, a musician-led national organization that puts together benefit concerts and awareness events in response to the Trump administration. She also performs in the fiddle duo 10 String Symphony with Christian Sedelmyer. Her 2017 album Shame was produced by Mandolin Orange's Andrew Marlin.
