Kolb was born in Hartford, Connecticut, on February 10, 1938 (many sources erroneously state her birth year as 1939). As her father was the music director of WTIC there, she was exposed to music early, meeting musicians. She went to jazz clubs with her parents.
Kolb was the first female American composer to win the Rome Prize, in 1969–1971. Kolb's composition Soundings was premiered by the Chamber Music Society of Lincoln Center in 1972. It was performed in a revised version for orchestra in 1975, played by the New York Philharmonic conducted by Pierre Boulez, with the orchestra positioned in three groups on the stage. She received commissions from the Fromm Foundation at Harvard University.
From 1979 to 1982, Kolb served as the artistic director of contemporary music at the Third Street Music School Settlement, where she presented the "Music New to New York" concert series, a series that featured composers from outside New York City. Additionally, she had a teaching career at Rhode Island College and at Eastman School of Music as a visiting professor in composition, as well as an association with The MacDowell Colony. She developed a course in music theory course for blind and physically disabled people from 1982 to 1986.
A selection of Kolb's compositions were featured at the Kennedy Center in Washington, D.C., performed by the Theatre Chamber Players in 1992, including the American premiere of Voyant and the world premiere of Introduction and Allegra for guitar.
Kolb's music was sometimes inspired by literary and visual arts. It features sound masses, often in vertical structures through simultaneous rhythmic or melodic units (motifs or figures). Kolb's musical style can be identified by her use of colorful textures, impressionistic touch, and atonal vocabulary. Some compositions are influenced by minimal music, some feature "a distinct jazz influence".
