I was at Eleveation Boston#2 (the show filmed for the DVD), and in my 30+ shows, that one quite possibly could have been the best (despite my crappy seats). You just can't capture a good live performance on DVD.
I've seen this band all across the country, and a U2 concert in Boston just feels different. The crowd is more energized, and there is clearly a special connection between the band and the city and its fans. If you compare Boston to NY, LA, and Chicago, its a relatively small city, yet they are playing 7 shows there this tour. I think that says it all.
