Yeah...it is a great album, but I wouldn't say that he's reinvented himself. He has certainly dabbled in all of these styles in the past. It is a great album though, and he is one of the few artists that manages to put out material decade after decade that has the quality of his first decade. You can't really make that claim about too many musicians these days.
The best new music is by a guy who is 60.
If you have not heard "LOVE & THEFT", new music by Dylan, you are missing out on one of the better releases in recent years. You do not need to be a Dylan fan to appreciate this--if you like almost ANY kind of music, you will be moved. In fact, if it weren't for his trademark grizzled vocal twang, you might not recognize the music as his at all! At the age of 60, he has re-invented himself. It is not fair that we had to wait 25 years for the next great Bob Dylan album!
