With three tracks drawn from their 1974 country-rock masterpiece Grievous Angel, a casual backstage take on the Flying Burrito Brothers' "Sin City," and a trim alternate version of Gram Parsons' wistful signature tune, "Hickory Wind," this EP neatly introduces Parsons and Emmylou Harris' dolorous, drawling harmonies. The cryptic heartbreak of "$1000 Wedding" recalls George Jones, and "Return of the Grievous Angel" exudes a rock-Gomorrah vibe. It all cuts to the quick.
