I have the Stornoway album on my list of things to check out so will look forward to that, surprised to see The Decemberists so high up on your list - I have all of their albums, even the overblown concept albums, and couldn't get into that one.
I also think the Nadine Shah and Lonelandy...
The new Buena Vista Social Club album, featuring odds and ends from the 1998 album is also brilliant.

I would say it is his best, slightly better than Illinois.
The new Mountain Goats album is streaming on NPR.
