Rachael Sage + Rachelle Garniez + Greta Gertler and more

Ladies who love keys lead a "Piano Driven Women" benefit for Mill Street Outreach at Joe's tonight. The talent includes Rachelle Garniez, an accordion-wielding chanteuse lately affiliated with Jack White's Third Man Records, who sets her breathy, mannered vocals to backdrops ranging from Weimar café balladry to tear-in-your-beer honky-tonk. Plus expat Aussie Greta Gertler, who works a ’70s-singer-songwriter vibe.
