Can you name any Christian Roots Rock Bands?

Looking for names of any Christian Roots Rock bands.  

What is "Roots rock"?   Wiki defines it as "a style of rock music that draws material from various American musical traditions including country, blues, and folk."

Secular bands or artists I'm thinking of include CCR, The Eagles, Los Lobos, Little Feat, Freddy Jones Band, Blind Melon, The Why Store, Storyville, The Wallflowers, Uncle Tupelo, Hootie & The Blowfish, The Badlees, Los Lonely Boys, The Subdudes, Cracker, Son Volt, Steve Earle, The Jayhawks, Wilco, Black Crowes, etc.     Not quite straight Southern rock or straight blues but incorporating those traditions.
