You should check out the documentary Seven Signs. Alot of the guys I mentioned (The Legendary Shack Shakers, Munly, Slim Cessna, Pine Hill Haints, on and on) are in that film. Alot of the doc was filmed around where I live (for the good and the bad lol) because the lead singer from the Shack Shakers (and several band members) are local guys. The lead singer Col. JD Wilkes produced the film and it has won awards across the US for best doc. It only came out on DVD a couple of months ago. I have a link on my myspace to it

my myspace

I think it is still on my top friends. The site has previews and some cool music playing. I think it has Slim Cessna if I remember right.
Take it easy man
