At your page for the hymn "The Heavens Declare Your Glory" (https://hymnary.org/text/the_heavens_declare_thy_glory_the_firm), there is a lovely choral audio recording of this hymn. (see https://hymnary.org/media/fetch/152390)
Does anyone know what choral group is singing this piece? Can anyone refer me to more music by these artists? I'd be delighted to purchase more of their work. They do a lovely job.
