Ok, it's starting to spread, Welcome to the Pond has made their own list (http://rfduck.blogspot.com/)
Here's the top 3
My favorite right now is The Best of the Bothy Band. It's full of great stuff, especially if you like high-energy Irish tunes!
15 years by Groupa is a very earthy, jazzy, beautiful collection. If the Bothy Band came from Sweden, they'd sound like this.
Live! From the Left Coast is probably my favorite album by Cajun band BeauSoleil. It's also the last album of theirs I've bought. What took me so long to get this gem?
