You also might consider modern music based on traditional themes and arrangements. One of the best performers out there is Brendan Nolan. You might get a copy of his CD titled "Across the Great Divide" from Old Sagousha Music, at 5160 Mayfair, Montreal, Quebec, H4V 2E9, Ph:(514)488-6734Some of the best on this CD are "Far From Their Home", "Beresford", "North of the Rio Grande". They are simple but beautifully crafted. Also "The Widow's Walk".
All the best, Mick
