Laura Pawel and her ensemble of dancers and musicians will present the premiere of "Plain and Fancy," along with company favorites, including "How are you is a greeting, not a question."   The Pawel style blends set choreography and music with sections of improvisation in the movement, music, and talk.   All dances are accompanied by live music performed by composer/musicians Phil Stone (keyboard), The Cecilia Coleman Quartet, and Barebones (guitar and harmonica).
