This year's edition of Chicago's annual Lollapalooza festival was the largest ever with over 100 acts and 270,000 people for the 3 day fest. The absolute highlight of course was the Foo Fighters wrapping up the gig on Sunday night. And not just because they're the Foo Fighters. But also because of the torrential downpour that caused a brief delay, until Dave and the boys went on and played for 2 hours in the rain. It's awesome. In case you missed the live YouTube stream here is the whole thing, rain delay included. (Fast-forward to about 15 minutes for the Foos.)
