I first heard this album when I bought a tape deck (reel-to-reel) from my brother in the early 70's when I was in my early teens. A recording of this was included. I knew who it was, but didn't know the name of the album for a long time as the box was unlabelled. I remember being struck with how clean it was, and enjoyed the standards on it (Circle Game, For Free, Big Yellow Taxi), but didnt' think too much about it. I rediscovered the album as a heartbroken 21 year old, and was stunned at the words that Joni had penned. They spoke to me so directly and with such insight, she'd been where I was.
This album comes in and out of my life, much like some people do, close friends who you may only connect with now and then, the time with them is so intense, you almost can't do it on a regular basis, but they are so valuble to you. This and most of Ms. Mitchell's other mid-period work are like that with me, when I'm in a time loss or reflection, they come out.
Anyway, can't add too much musically to the already written reviews, except that I hope people really listen to the words (and read them to get them all) because she is saying some amazing things here.
