In 1990, a year before beginning her master's degree in choral conducting at the University of Illinois at Urbana–Champaign, Kristina Boerger decided to form what she advertised as a lesbian/feminist chorus called AMASONG.

In the PBS documentary produced by Jay Rosenstein, entitled, The AMASONG Chorus: Singing Out, Boerger explained, "There's lesbian-feminism with a hyphen, which refers to woman who are lesbian and feminist.

[2] Past directors include Jill Crandall, Meagan Johnson, Esther Gille, Margot Rejskind, and Deborah Skydell.

She is currently Director of University Choirs at the DePauw School of Music, where her Chamber Singers have performed by invitation at the White House.

Each summer Boerger joins the faculty of the Madison Early Music Festival as a conductor, soprano, and course instructor.

In addition, she has recorded for Bobby McFerrin and collaborated on works for movement and vocal ensemble with the Christopher Caines Dancers.
