Recorded between 2020 and 2022, some of Deleyaman's lyrics on The Sudbury Inn are partly inspired by or make direct references to the "Tales of a Wayside Inn" written in 1862 by the American poet Henry Wadsworth Longfellow about the real stories of seven travelers telling their tales at the Wayside Inn in Sudbury.

Six musicians have joined Aret Madilian and Beatrice Valantin, founders of Deleyaman, during the recording sessions of The Sudbury Inn.
