These gems from throughout Gram Parsons' career reveal the Americana icon to be not just a great country songwriter, but a masterful interpreter as well. On "Close Up the Honky-Tonks," he and The Flying Burrito Brothers speed up a Buck Owens classic, adding a little irony without diminishing the heartbreak at the song's core. Parsons' take on "Knee Deep In the Blues," meanwhile, is loose and rollicking—almost garage-rock-esque.
