Parsons completists will dive eagerly into this cache of rough-edged 1972 boom-box demos that reveal the process leading to the tragic country-rock legend's debut album, GP. Along with singer Emmylou Harris and fiddler Rick Grech, Parsons teaches and workshops standards like "Streets of Baltimore", as well as original tunes (including the melancholy "A Song for You" and confessional "How Much I’ve Lied") that would enter the country canon and never-recorded gems like the defiant blues "Ain't No Beatle, Ain't No Rollin’ Stone".
