I'll insert a shameless plug here for Jody's sister Janet Stecher, who is half of Rebel Voices (Susan Lewis Graham is the other half). They are of a different kind of "tradition" than Jody and Kate, concentrating on songs that have come out of the labor movement and the women's movement, but their harmonies (mostly a capella) are brilliant and their musicianship is impeccable. Runs in the family.

Aloha,
Mark
