content: This is a two CD collection. I have been listening to CD one over and over. It is unfailingly brilliant, and sounds more modern that most of the tracks on the top 20 today. Wonderful work, and as other reviewers have noted, don't worry about there being two recordings of the same track - the dub versions are significantly different to the single or album versions and equally as enjoyable (kind of like going to see the band live rather than listening to the LP).I was less impressed with the second CD. There are great tracks there too but it is less consistent.If you are looking to buy the best of Grace this is the best way to do it in one purchase. Other "Best of Grace" collections don't stand up to this period in her recording career.
