After studying with poet Ted Berrigan at Northeastern Illinois University in Chicago, she moved to New York City and became involved in a number of individual and collaborative projects on the downtown poetry/music scene in the late 1970s-1990s.
She performed frequently at venues like The Kitchen, Bowery Ballroom, St Mark's Poetry Project, Bowery Poetry Club, Nuyorican Poets Café, Fez, CBGB, Luna Lounge, Sidewalk Cafe's The Fort, Mercury Lounge, Galapogos, The Sculpture Center, The Open Center, as well as One World Poetry Festival (Amsterdam) and The International Festival of the Poets (Rome).
With writer Maggie Dubris she co-founded the all-women cult band "Homer Erotic" (1991 to 2000), which came to life during a lull in poetry readings in the early 90s.
She has also performed with Pauline Oliveros, Elliott Sharp, Z'EV, Janene Higgins, Monique Buzzarté and other experimental artists and musicians.
Barg has contributed to numerous sound art anthologies, including Elliott Sharp's multi-artist compilation CDs State of the Union, Beneath the Valley of the Yahoos, Phone Noir (with Fem Noir), Late 20th Century Sexual Practices, One World Poetry (a multi-artist compilation recorded at Amsterdam's One World Poetry Festival), and Sugar Alcohol & Meat (produced by John Giorno Poetry Systems).
