We are the Seattle Metropolitan Singers and the Offbeats Vocal Jazz Ensemble. More info: https://t.co/wmBEs9gFxm. FUN PEOPLE... SERIOUS SINGING! Seattle Glee Clubs' two choirs offer adults opportunities to sing jazz and traditional choral music. Seattle Glee Clubs is a community-based music organization that is committed to providing adult amateur singers with choral experiences that are rich, rewarding and fun. We are also dedicated to sharing our music with our audiences to deepen their appreciation of the music we perform, and to demonstrate the joyous and important role music can play, even in the lives of busy adults.
