Ok, well now I've heard about 15 songs so I have alittle more information. So, to my ears I here a few things. The Blues, Celtic/Irish music and Jazz. Oh yeah and alittle rock (60's blues/rock). Im not sure why you say that jazz and rock wouldn't be useful to you, just the tone of the bass is pure growly jazz and the arrangments sound very rock to me. But, I realize we hear different things so another idea I have is the band Lunasa. You might find some interesting ideas there.
