The 11 PM concert, which takes place before Milligan leaves to star in the national tour of the Tony-winning musical Kinky Boots, features Tony nominee Laura Osnes, Matt Doyle, Amy Jo Jackson and Michael Gioia.
Andy Einhorn (Bullets Over Broadway) is musical director of the concert, which is conceived by Milligan.
Here's how 54 Below bills the evening: "A Midwestern preacher's daughter, Bonnie grew up in a trailer without much money, dreaming of performing someday. When her parents divorced, she moved to Ohio. While attending college at Ohio State, a mentor told her she'd 'never make it as an actress, because of the fat thing.' Fearless up until that point, those words killed something inside of her. Upon moving to New York, Bonnie auditioned here and there but was typed out a lot — and started to hear the words of that mentor in her head, louder and louder. One day she decided to take a voice class at the Linklater Center, and during the class, she realized just how much those words 5 years earlier had affected her. After some therapy, Bonnie finally began to feel more confident and self-loving. She went to an open call at the Flea Theatre and got in! There, she met some incredible artists and began making connections – including with director/composer David Dabbon and writer Dick Scanlan, who asked her to premiere a new song in a concert. One thing led to another and before long, Bonnie was heating up concerts from 54 Below to Joe's Pub, with an agent, and a national tour to boot!"
