I'm glad you've taken the path to enlightenment, it's a shame so many people shrug U2 off as crap stating reasons such as "Bono is a prick" or "The Edge can't play guitar"
They (like Bruce Springsteen) can transcend a mere live event into a spiritual experience. I love U2 when they play to their strengths, sadly they've reverted back to the old ways of style over substance recently ala the Popmart shows.
The live from Chicago DVD is the band at the peak of their powers -
Some of the transitions from song to song are amazing.
