Anything with Gene Clark present is worth investigating, this complete collection of all the Dillard & Clark back tracks is a perfect example of this.
The music shows the commercial birth of Bluegrass tinged country rock and mildly rocking country rock. Alison Krauss must have listened to these recordings many times!
Although the musical content is great the liner notes are not too helpful. There are no clear song writing credits anywhere and no mention of the female singer on the first album...who was she? Donna Washburn is present on the second album tracks, was she there on the first as well?
To summerise - a great bunch of historic recordings (with some mild filler tracks, as expected) but poor specific player/writing credit information, hence a star dropped. Looks like a trawl through the web is required...
