Her father was a professor of music theory and composition; her mother, an oboist and pianist. Andrea herself took up the violin, but began fiddling at age ten when she outgrew her classical training. The combination of bluegrass improvisation with classical elegance would influence her sound for years to come.

Zonn arrived in Nashville at 16 and soon found work as a studio musician. In 1990, she joined Vince Gill's band and continued to perform with the country superstar even as she collaborated with such luminaries as Lyle Lovett, Alison Krauss, and Trisha Yearwood. Zonn made her solo debut in May 2003 with Love Goes On (Compass). The LP included tasteful contemporary bluegrass, country, Celtic, and pop influences and featured Zonn's violin and soaring soprano throughout. ~ Johnny Loftus
