I forgot about this thread and that I was added to it. I'm with PC, who at the time said that's "pretty good" but that he "hears a lot of problems". Truth be told by this time I think it's easiest and perhaps most musical to perform fiddle tunes completely solo without anyone accompanying the bass. In a solo setting there is more opportunity to us double-stops and glanced open strings to create a totally separate layer of harmony and rhythm than the actual melody line. In a great studio with a proper mic and acoustics all of this can really pop out of the mix and be heard and felt. I still duet with people now and then and I feel like it's getting better with time. One major change for me in the last year has been using solo strings and a more soloistic set up on the bass. My bass completely changed with the solo strings and the lower string height and almost immediately sounded quicker, deeper, more precise and more resonant. Everything I'd been fighting before became much smoother and more musical. Now it's difficult to want to pick up the bow in standard tuning because in the back of my head I know how much better it could be with my bass in solo tuning.
This is another old clip, standard tuning and regular strings. It's still clunky to my ears now but it's a step up from the post from years ago. And one can hear a fiddle tune as a live duet. Rhythm and drive are so important and I think we got in sync after a few passes and you can hear a hint of the possibilities in this set up. I remember the sound people were totally trying to get the balance right while we were playing as we had no soundcheck which was distracting but hey, that's live performance...Maybe this is a little better, payed a few years later.
