From what I’ve seen/listened to so far, numerous good shows. The ones I’ve enjoyed the most so far:
Beastie Boys in London.
Jack Johnson in Australia.
Linkin Park in Tokyo.
For those that enjoy Linkin Park, this concert was incredible. They put on a heck of a show and, compared to the rest of the acts at various concerts, they have a HUGE set list. It’s basically like watching a DVD of a concert. And one of the lead singers spends a couple minutes talking in Japanese. I was impressed.
As for the environmental/political side of things, I’m ignorant. I still haven’t see An Inconvenient Truth. Sorry Al.
