Flutist Jonathan Rider and pianist James Fox will perform to a lunch time audience at All Saints’ Parish Church in Gainsborough on Tuesday 31st July.
It will be the second on a series of free lunch time concerts this summer.
Every Tuesday throughout July and August, visitors can enjoy live classical music free of charge.
The concerts were introduced in 1992 to bring live music to visitors and local people who are in town for work or shopping on a market day.
And they have developed into an annual series - this year being the 21st.
Each concert is at 1.05pm.
