Meeting Point

Looks good! I’ve heard of Aly Bain, but not Bruce Mollsky. Question, though: Are most of these tunes original compositions, since many don’t link to anything? Will have to give it a listen!

The tunes aren’t here because they because they are not tunes you would normally find played in an Irish session. I would be willing to bet that none, or very few, are original compositions.
You made the similar assumption about the "High Level Ranters" recordings.
If a tune hasn’t been posted here and there’s no "link" on any "non-Irish" recording, the above is the most likely explanation. Assuming they are recent or original compositions is quite possible, but I would say much less likely.
Hope this helps. Regards, Kenny.
PS - Bruce Molsky is an absolutely brilliant musician - at what he does.

Good to know. I’ve never of "The Hills of Mexico" before.

I too am surprised you hadn’t heard of Bruce Molsky - especially with you being a fellow American and whatnot. I don’t listen to him much, but I do know he’s a very good old-time fiddler.
