The Red River Chapter of the American Theatre Organ Society (RRATOS) was founded in 1965 - ten years after the start of the parent organization, ATOS. Its membership is comprised of organ enthusiasts, organists, and technicians from the Fargo/Moorhead area. It is one of over 83 chapters in the US, Canada, Europe, and Australia.
RRATOS owns two Wurlitzer organs that are used regularly and is a nonprofit 501(c)(3) organization. The chapter hosts an annual Silent movie night at the Fargo Theatre, provides accompaniment for Minnesota State University's Summer Cinema Series, and produces noon hour Holiday concerts in December. RRATOS also provides organists for movie prologues and special events at the Fargo Theatre.
In October 2018, RRATOS released a strategic plan outlining its goals to stay relevant and active for many years to come. Some areas of focus include developing youth outreach programs, increasing the frequency of public events, introducing the pipe organ to new audiences, operating with a professional non-profit mentality, and continuing our restoration efforts on our instruments.
