Bluegrass offers insight into the variations within the genre, from the mesmerizing vocals and skillfull instrumentation of Alison Krauss and Union Station's Every Time You Say Goodbye to Railroad Earth's contemporary new-grass sound on Been Down This Road. Then there s the lively rendition of Jackaroo, by legends David Grisman and Jerry Garcia, alongside the soft, contemporary sounds of Andrea Zonn with Alison Brown. Frank Solivan's Across the Great Divide and Peter Rowan's Man of Constant Sorrow, transport listeners with their earthy, new-grass style. James Alan Shelton brings his beautiful melody-oriented guitar playing to the traditional song Shady Grove, and Crooked Still adds a modern bluegrass sound to New Railroad. One of bluegrass music's longest performing groups, The Seldom Scene, provides their distinctive vocals and picking to the Dylan classic Boots of Spanish Leather followed by the versatile all-girl string band Uncle Earle The Last Goodbye. Young North Carolina natives Town Mountain contribute their original, traditional bluegrass stylings with Diggin' On The Mountainside, while the inimitable Sam Bush, brings his beloved mandolin playing to Diamond Joe. The album closes with a rendition of the gospel favourite I'll Fly Away, performed by a variety of talented artists.
