I just got "Chaos And Creation In The Backyard" a few days ago. I haven't listened to it yet. To be honest, I was fairly disappointed with "Driving Rain", and I kind og gave up collecting and following his solo career. I absolutely LOVE the song "My Valentine". I would put it up against his greatest songs, like "My Love", "Let It Be", and "The Long And Winding Road".
I like about half of Driving Rain. The opening song, Lonely Road, really had me optimistic when I first heard the album, but then it settles into MOR McCartney pretty fast. I do like the album closer Rise the Raindrops. I used to really like Freedom when it first came out, but I think I was still too caught up in post 9-11 Patriotism to realize that it's a pretty mediocre song. Good message, so so execution.
