Query: Ruth has a Melissa Etheridge passion with a Kate Bush voice.

A must-have for the lover of chick-rock in the strains of Melissa Etheridge, the Indigo Girls, early Sinead, Shawn Colvin, etc.A powerful singer with breathtaking control, who can move you without ever taking herself too seriously.
