Way too trim for its own good?less than 20 minutes and no extras?this 1963 masterclass in straight-backed country picking was the Rosetta Stone for a whole slew of West Coast wannabes (Gram Parsons once said he would give his right knee to be in the Barkers). Including 17-year-old mandolinist Chris Hillman and fellow future Burrito Kenny Wertz on banjo, this stunning acoustic fling was the torch-passing of Monroe, Flatt and Scruggs to a hip new generation with no regard for traditional country/rock boundaries.
