I just saw this duo at the BRPAC in Hendersonville, NC. They were great! Ashley's F5 almost didn't need a mic, it projected so well... it was a 100-seat theater, though.
What do you guys call a mix of celtic, jazz, and old-time? I can't pin it down, but celtic doesn't have that jazzy dissonance that these two love.
If you have the opportunity to see these folks, do it, you won't be disappointed.
