This document of the rougher end of the 'Outlaw Country' movement of the early 1970s has acquired something of a legendary status, largely because it is so hard to find without spending mega-bucks.
In truth, the best bits (which are indeed sublime) can be viewed on YouTube. The two songs by Townes Van Zandt, especially 'Fixing To Die', are spine-tingling records of a great songwriter before his fall.
There are many other good passages, but the amount of footage given to David Allan Coe is an embarrassment that probably explains why the film-makers have not re-released it. Coe brags about his exploits in prison, exploits that were later revealed to be untrue, and the sequence where he plays to the prison crowd is cringeworthy.
These were musicians who subverted the glitzy Nashville image of country music and who paved the way for the more rootsy Americana genre. It's a shame that this lumps them in with Mr Coe.
