The City of Brotherly Love meets the City of Blinding Lights

I'm off to Philly in the morning to visit my friend Andy and see back-to-back U2 concerts. This will be my first (and second) U2 shows, and I'm pretty fired up. I'm in the midst of listening to their entire catalog on shuffle, and that's only increasing my enthusiasm. I've heard they're leaning pretty heavily on How to Dismantle an Atomic Bomb in the setlist, but throwing some older gems in there as well. And they've been changing the set from night to night, so we don't have to worry about seeing the same show twice. Should be a good time, and as always, a welcome excuse to get out of town for a few days.
