The Bowl, designed and built by Green & Wilson of Waterville, was the practice and performance hall of Eastern Music Camp on Lake Messalonskee in Sidney. It was built in 1931 when the camp acquired the property.

The stage is 100-feet wide, 45-feet deep, and 65-feet high. It can seat a 500-piece orchestra. The clearing in front of the Bowl can accommodate a crowd of 3,000.

The Bowl is still standing as part of New England Music Camp.
