After completing her education, Anderson spent time as a freelance composer, orchestrator, and choral arranger for NBC-TV, and later for Lincoln Center Theater.

"[7] Her collage piece SUM (State of the Union Message) is included on the Lesbian American Composers collection (1973 Opus One, reissued 1998 CRI: 780).

[9] Anderson received degrees in flute and composition at the University of Washington and later studied with Darius Milhaud and Nadia Boulanger in the 1950s and with Vladimir Ussachevsky and Pril Smiley in the 1960s at the Columbia-Princeton Electronic Music Center.

[9] Just before her death in November 2019, Anderson approved the test pressings for an LP of her work, entitled Here and released by Arc Light Editions in February 2020.

[10] Included are: ‘I Come Out Of Your Sleep’; ‘SUM’ (which uses TV advertisement samples to mimic a speech by President Richard Nixon); 'Pregnant Dream' (a collaboration with poet May Swenson); ‘Points’ (constructed entirely from sine-waves); and the electro-acoustic 'So What'.
