In her teens, Garth studied privately with Armin Watkins, a respected pianist and faculty member at The University of South Florida.

Garth made her New York recital debut in Merkin Concert Hall with a program of solo and chamber works by Alban Berg that included the Chamber Concerto for Piano, Violin, and Thirteen Wind Instruments, conducted by Harvey Sollberger.

[4][5] During John Cage’s centennial year, she gave multiple performances of his landmark work for prepared piano, Sonatas and Interludes.

In addition, her performances have been heard on major radio stations, including WNYC, WQXR, WBUR, Radio Suisse Romande (Geneva), and the BBC Radio 3 program “Music in Our Time.” Garth has been lauded for her “exquisite ear for piano sound”[6] and for “a touch that allowed for almost ethereal transparency.”[7] In response to one of her live performances of Donald Martino’s Fantasies and Impromptus, New York Times critic Bernard Holland stated that “[o]ne can think of no one better qualified to play this intricate, shining music.”[8] New York Times critic Anthony Tommasini included Garth's recording of Fantasies and Impromptus in a Times listing of his five favorite recordings of music composed since World War II.
