Tim Delaughter mentioned their show was the first of that size that would be featured as part of the Millenium Stage program. The Kennedy Center acts as a perfect backdrop. The plaza has space for about 5,000. I'd say about 2,000 showed up which gave plenty of room for moving about. The crowd make-up was very diverse; toddlers, elderly, hipsters, hippies, young professionals coming off of work, etc.
There were clearly many people there just because it was a free show. This is exactly the kind of person a band like the Polyphonic Spree would like coming out... to expose another segment of the public to their music. Major kudos to the Kennedy Center for arranging this. The Millenium stage is such a great idea and gives people the opportunity to see live performances who normally would not be able to afford it.
The Polyphonic Spree fed off the energy of this performance and really put on a great show!! What a cool night.
By the way, kennedy-center.org will archive this show on the website so it can be streamed on your computer.
