"This well known 1968 album is a pun on the fantastic expedition of Lewis and Clark, the famous leaders of the USA's 'Corps of Discovery' who were the first east coast Americans to successfully negotiate the north west passage to the Pacific Ocean in the early 19th century. Of course this ties in beautifully to the John Evans story featured in American Interior - Lewis and Clark used the maps he created between 1795-7 (whilst searching for a mythical tribe of Welsh speaking First Nation Americans) for the first year of their expedition. There's a keen sense of the rhythm of exploration on this fantastic record. Dillard's peerless banjo picking could easily power a steam boat up the Missouri River and Clark's melancholic musings on songs like 'Train Leaves Here This Morning' give a clear sense of long distance travel and loss. Meanwhile a team of proto Country Rock greats including Bernie Leadon, Sneaky Pete and Chris Hillman play away busily in the background, setting the benchmark for the mellow mountain sound that would dominate the airwaves the world over in the following years."
