Here's a little something from Dillard & Clark, 'Train leaves Here this Morning' and 'In the Plan.'
It's off of a great album they cut back in 1969, 'The Fantastic Expedition of Dillard & Clark'. If you don't know who Doug Dillard and Gene Clark were, you should. Anyway if you like bluegrass/country give it a listen. If you don't, give it a listen anyway. These guys were exceptionally good.
One more track by Allison Krause and Robert Plant of 'Through the Morning, Through the Night' which gives the Dillard & Clark standard a run for its money.
