Rosanne Cash, Emmylou Harris, Lucinda Williams (photo: Ria Burman) Rosanne Cash, Emmylou Harris, and Lucinda Williams country-folked SFJAZZ on Thursday night, taking turns to sing and support with humdinger harmonies, sweet storytelling, and bright banter. Williams' foot-tapping, bluesy tunes and down-to-earth demeanor, Harris' captivating, voice complemented by finger-picking folk, and Cash's engaging, poetic, lyrical storytelling all made for a dynamic, thrilling trio. Add top-notch, spellbinding support with piano and guitar mastery accompaniment from John Leventhal, and the night rocked like folk.
