I discovered Gillian Welch purely by chance, hearing a minute or two of her music on a TV show about modern female 'country' artists. I was amazed at what I heard, wrote down her name, and went out and bought some of her material, including this. It's one of the best CDs I've bought in the past two or three years. And primarily being a rock music fan and musician, who never buys 'country' music, that surely indicates that Welch goes way beyond the constraints of any particular format.
As other reviewers have noted, it's a very stripped-down sound, almost reminding me of early Dylan. I find her, similarly, a rather enigmatic artist, and the last song on the album is unusually long, very much the sort of thing that Bob Dylan sometimes goes for. But there's humour in it, too, it's not all serious stuff. And that was also a classic characteristic of Dylan's early work.
Despite the rather basic two-instrument plus one (or two) voice line-up seeming a bit restrictive, in practice it isn't restrictive at all. In fact, I think it's an advantage. Each song has its own musical character, and that's because Welch (and friend!) are highly creative, and don't need to alter the instruments etc to get variation in their overall sound. They've got plenty to say, and they don't run out of ideas. Gillian Welch is surely a major 'find' who deserves a much higher profile, and I'm sure she'll get it. In a somewhat unusual move, the CD includes a 'live' track, which sits very well with the studio numbers. A great album!
