Kathy Mattea's 2012 album folllows the same Appalachian theme and is as good as Coal.
The following links are of songs from the album that she sings outdoors - minimalist studio !

Two song by Laurie Lewis
The Wood Thrush Song
http://www.youtube.com/watch?v=9Xz6QjNwL-Y
Man is the inventor, the builder, the sage
The writer and seeker of truth by the page
But all of his knowledge can never explain
The deep mystery of the Wood Thrush's refrain
Now the Wood Thrush has vanished, seeking the place
That's not felt the crush of Man's embrace
The steep woods are gone now, and oh, how I long
To again feel the spell of the Wood Thrush's song
The Maple's Lament

But now that I am dead the birds no longer sing in me
And I feel no more the wind and rain as when I was a tree
But bound so tight in wire strings, I have no room to grow
And I am but the slave who sings, when master draws the bow
But sometimes from my memory I can sing the birds in flight
And I can sing of sweet dark earth and endless starry nights
But oh, my favorite song of all, I truly do believe
Is the song the sunlight sang for me while dancing on my leaves
Now is the Cool of the Day
