Ok, on the hunt for this one:
Heartworn Highways is documentary film by James Szalapski whose vision captured some of the founders of the Outlaw Country movement in Texas and Tennessee in the last weeks of 1975 and the first weeks of 1976. The film was not released theatrically until 1981.
The documentary covers singer-songwriters whose songs are more traditional to early folk and country music instead of following in the tradition of the previous generation. Some of film’s featured performers are Guy Clark,
, Steve Earle, David Allan Coe, Rodney Crowell, Gamble Rogers, Steve Young, and The Charlie Daniels Band. The movie features the first known recordings of Grammy award winners Steve Earle and Rodney Crowell who were quite young at the time and appear to be students of mentor Guy Clark. Steve Earle was also a big fan of Van Zandt at the time.
