Carr graduated from the University of Iowa in 1972 with an honors degree in English. She went on to work as a freelance writer for several years, and then as a staff writer for The Village Voice from 1985 to 2003, where she specialized in arts coverage. "On Edge," her column for The Village Voice, chronicled New York's downtown performance scene, including such then-emerging artists as Linda Montano, Tehching Hsieh, Marina Abramovic, and Ulay. She also wrote about performance art and culture for ArtForum, LA Weekly, Interview and Mirabella.
Her 2012 biography of artist and AIDS activist David Wojnarowicz, Fire in the Belly, has been called one of the most important books of the year for its meticulous analysis of Wojnarowicz's prominent role at the intersection of gay history and art history in late 20th century America. The book won a Lambda Literary Award in 2013 in the category of Gay Memoir or Biography.
