As part of the Washington Non-profit, the Dissonance, this big band is made up of mostly Microsofties and ex-Microsofties. When the MJJO is in the house, there are sure to be swing dancers too. You can hear them regularly at Crossroads of Bellevue, Third Place Books in Lake Forest Park, and Tulas. They also do private parties and corporate gigs. Their vocalists are stellar, rhythm section sublime, and sax section second to none.
