This is by far the best album I have bought in a long time. It took a few listens for me to get in to it, I think because it was a bit different from Amy's previous albums so not what I expected. However, once I learnt the songs, I couldn't stop playing it and now its on once or twice a day. Easily Amy's best solo album so far, but I do like the edgy sound of Live from Knoxville which includes material from her previous albums.
If you like the Indigo Girls, you might be surprised by Amy's solo material. Its very different in musical style, but easily on a par (if not better) in terms of quality. Musically, its a lot more rocky than IG, and the lyrics are more 'daring' in some respects. So, if you like IG but want to listen to something with a more rock/punk quality give this a try.
