I searched the forum and didn’t find any discussion of this release. I found the recording a while back and think it’s really good. I believe Bandcamp will allow a few listenings before they want you to purchase it - which I did. If this album has been discussed, please direct me to that discussion as I’d like to read it. Hope my link works.
Nick is no slouch as a fiddle player either. I believe Nick is playing fiddle on 4 of the tracks. Not too hard to tell them apart as fiddlers. That's Mitch on Pretty Polly. This info is contained in the liner notes which comes with the download. I'll definitely check out the performance you've linked.
