Rock's "Grievous Angel"

Singer and songwriter Gram Parsons infused country sounds into rock during the 1960s and early ‘70s, both as a solo artist and a member of the Flying Burrito Brothers, the International Submarine Band and The Byrds. (Some credit Parsons with the countrified sounds on the Rolling Stones’ "Exile on Main Street.") We talk with David N. Meyer, author of the a new Parsons biography, Twenty Thousand Roads.
