I saw the Secret World tour in San Francisco, LA, San Diego, and Sacramento.  This was the high point of Peter Gabriels concert tours, far surpassing Shock the Monkey and Growing Up.  The visuals on the DVD are somewhat grainy, some of the content has been overdubbed, but the choreography by Robert Le Page are well captured here.  Sound quality is outstanding, and if you have a surround system, you will love the drumming of Manu Katche.  Highly recommended.
