Way ahead of it's time, and so unjustly forgotten, The Fantastic Expedition of Dillard & Clark is a brilliant album. The only criticism is that is was a bit short, and a couple of tracks have been inserted in the middle to bulk it up. One of these, Why Not Your Baby, was probably intended as a single and is OK, but not up to the other material. The styles vary from Byrds (Gene Clark was, of course, a singer in the Byrds), Country, Blue Grass, and Folk. There is a lot of banjo, mandolin, harmonica, and fiddle and, together with Gene Clark's supreme voice, the sound of the instruments is one of the pleasures of the album. The songs are great too, and Train Leaves Here This Morning, and With Care From Someone are absolute classics.
Also on the CD is Through the Morning Through the Night which is more Country in style. There are a lot more covers and it is overall less satisfying (hence why the whole only gets 4 stars), but the title track and Polly (both covered by Plant & Kraus on their Raising Sand album) are both excellent. Indeed, you have to admire the courage of Plant taking on Polly after hearing Clark's effortless singing.
