Inspired by JohnM's suggestion, Kim and I have been working on Peg Leg Howell's Rolling Mill Blues. It represented a couple of challenges for both of us - for me, the singing dips kinda low out of my range, so it's hard for me to push air in those spots. I did end up taking some liberties with PLH's guitar part, but tried to keep the skeletal sound that he got. We tried to let the three parts weave in and out of each other - not sure how well that worked out... might also be affected by my "recording technique" (hah!).
Blues fiddling is a whole new thing for Kim, but I think she picked up the gist of the whole thing pretty quickly. As a result of working on this tune, she started fooling with positions beyond the 1st. The intonation up there can get a little dicey, but it's getting better all the time. This is also her first attempt at incorporating vibrato, which doesn't really have much of a place in old-time fiddling.
The overall recording is pretty rough - expect no finely honed recording techniques here - download at your own risk! The file is pretty small - about 600kb.
