Dereham Band will play at the Ellenor Fenn Garden in the town centre from 2.30pm to 4.30pm on Sunday, September 4.
The group performed at the same location on August 14, attracting a healthy crowd throughout the afternoon.
Jane Broscomb, band secretary, said: “Last time, a lot of people were walking past and hearing the band for the first time. The next concert will again have a relaxed atmosphere. People can come and go as they like and just enjoy it.”
This year, Dereham Band has not been able to use its usual summer concert venue, the Queen Mother’s Garden, which is currently closed due to ongoing renovation work.
