U2 playing in the rain? Fucktastic.
I think I paid 200 dollars for general admission.
Lets put this without a tad of exaggeration, I think $500USD would still be a very fair price to pay to see U2 just perform "Where the Streets Have No Name" like they did last night.
I also say this with any humility I have left from the exhilarating experience: fuck hearing them on CD, if you haven't listened to them live - you may never completely guage the true genuis that is U2. I've been to many concerts; I'd doubt any would come a shade close to the surrealistic, orgasmic heights of two hours of magic.
Where the Streets Have no Name (live): Priceless.
