This is the person who argues that Gram Parsons wasn't the creator of country-rock.
John Einarson, who wrote a book called "Desperados: The Roots of Country Rock (Cooper Square Press)
This is the write up on it by Bob Cannon in the July 10, 2001 edition of Country Weekly
"Nearly every artist on today's country charts pays homage to country rock pioneers like the Eagles, The Flying Burrito Brothers or Poco. But as historian John Einarson points out, those bands were by no means the originators of the music style.
Einarson gives credit to where it's due, going all the way back to Buck Owens' driving Bakersfield Sound and to the 1960s rockers like The Byrds and Buffalo Springfield. From there, he connects the dots from the Southern California scene of the early '70s to today's stars like Dwight Yoakam and Emmylou Harris.
Desperados is loaded with interviews with all the significant artists of the era, but what really makes the book enjoyable is Einarson's refusal to perpetuate myths. He rejects the theory that Gram Parsons invented country-rock, and points out that for all its historical significance, the genre was a commercial disaster until the Eagles took flight. Desperadoes also puts the spotlight back on long forgotten bands like The Dillards and Hearts and Flowers, as was all instrumental aces like guitarist Clarence White and the Eagles' Bernie Leadon, both of whom were always near the center of the action."
