Four years running, the Railroad Square Music Festival is a FREE day of music in Santa Rosa's Railroad Square.  The Railroad Square Music Festival is a project of The Lost Church, a non-profit organization dedicated to the belief that people need beautiful, intimate performance spaces to share their ideas, stories and arts. Their Santa Rosa theater is opening in 2018 and will help ensure that the arts have a place in the future of the North Bay.  

The main sponsors of the 2017 event were Lagunitas Brewing Company, Virginia Dare Winery, and the City of Santa Rosa.
