Bluegrass offers insight into the variations within the genre, from the mesmerizing vocals and skillful instrumentation of Alison Krauss and Union Station's Every Time You Say Goodbye to Railroad Earth's contemporary newgrass 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, newgrass style.
