Two of my all time favorites Eddie LeJeune (any album) and Horace Trahan (on the Ossun Blues album) do a bunch of songs in D. Also Geno Delafose does the Opelousas Waltz which is a great and simple waltz in D (the Amede Ardoin Opelousas Waltz, not the Austin Pitre Opelousas Waltz which is a completely different tune).
