Alt Country/Folk, American roots

My love for this style of music began about 14 years ago with the Billy Brag and Wilco tribute albums to Woody Guthrie titled Mermaid Ave. Volume one and two.
I just happened upon a new band , that I am very excited about!!! The Cave Singers They are from the Seattle area. Their new album is VERY, VERY solid.I also have been enjoying the band's two albums from 2007, and 2009 on Spotify !!
Also do check out The Wood Brothers !!!!!!!!!!!!
Chris Wood is the Wood from band Modeski, Martin and Wood.
The Wood Brothers three albums are near flawless.
I have seen the Wood Brothers twice. If you like em, a must see live.
MMW are some of the best concerts I have ever seen as well. MMW are more alt/Jazz/Jam band
Ryan Bygham's album Junky Star is a masterpiece!!
The Civil Wars album was fantastic, much deserved of the grammy it won.
I am a pretty big Son Volt/ Uncle Tupelo fan.
Wilco of course.
What say ye? Who or who are your favorite Alt Country Alt Folk/ American Roots bands or albums.
Thanks,
Todd
