I listened to this CD without any ideas of the musical styles that would be used. It was only through having heard solo songs composed by Robert Plant some years earlier (think "Big Log") that I wanted to listen to 'Raising Sand' to see what all the hype was about. When I heard the first few bars of each song I thought 'how the hell is this going to develop?' and then it would evolve and go somewhere I was not expecting it to go and it was quite pleasant and thought provoking. Some of the song arrangements will grow on me; a few of them I thought were good. I definately will be listening to this again. It is an album to chill out to whilst lying on the couch after a heavy day at work. The two vocal styles intertwine and complement one another and they take you off to explore new lands you've never heard about.
