The Estey 3-Manual Pipe Organ

History
The majestic pipe organ installed in the Sanctuary of Epsilon Spires was built in 1906 by the Estey Organ Company, founded in Brattleboro by Jacob Estey in 1872. The Estey factory manufactured more than 3,000 organs in its Brattleboro factory, shipping them as far as China and South Africa before closing in 1960. Our Estey was given as a gift to the First Baptist Church in memory of Juilius Jacob Estey (son of Jacob Estey) by his sons Jacob Gray Estey and Julius Harry Estey. The organ was revised in 1958 by Elroy E. Hewitt, but its tonal features remain for the most part untouched. The instrument is an excellent example of an early-twentieth century American pipe organ, and is one of the largest organs of its kind still in use today.
Organ Programming at Epsilon Spires

Epsilon Spires seeks to honor the history of our magnificent and unique pipe organ while expanding our audience’s expectations of what this versatile instrument is capable of, with a focus on showcasing experimental and secular works. Our innovative organ programming continues to breathe new life into this historic treasure, which is featured regularly in concert performances by talented international contemporary composers playing free recitals of their favorite pieces.
To transport audiences back in time with unforgettable, immersive experiences, we frequently invite accomplished silent film accompanists to perform live soundtracks to classic films activating our powerful pipe organ, which is similar to the organs that would have been heard playing in movie theaters during the original theatrical releases.
