Foley's initial career began in Ottawa, Canada, in 1984 at the age of sixteen where, in addition to solo work, she sang with the Back Alley John Revue. Foley sent a demo tape of herself to Clifford Antone's label (Antone's Records) in 1990. Impressed, the record label arranged an audition for the guitarist. She moved to Austin, Texas and soon signed a recording contract with Antone's. In 1992 she appeared on the bill at the San Francisco Blues Festival. In 2000 Foley won a Juno Award for Best Blues Album for Love Comin' Down.

Her 2007 album, Time Bomb, featured two other female blues players, Deborah Coleman and Roxanne Potvin. The opening title track, "Time Bomb", an instrumental where all three women take turns laying down leads, on the next nine songs the women trade off taking lead vocals and guitar duties of every third song until they come together again on the final track "In The Basement".

In 2010 she released He Said She Said (with Peter Karp).
