Bao Nguyen was a campaign staffer for Barack Obama. One of the lucky 4,000 few to snag an invite to the Obama Staff Ball on Wednesday night, Nguyen found himself at the last official event of inauguration festivities. Fortunately he also happens to be a great photographer, and was front and centre for the nights musical acts. Namely, some guys (and long time vocal Obama supporters) called Arcade Fire and Jay-Z. Ok then.

Nguyen wrote on US blog Brooklyn Vegan:

"Frankly, I could not ask for a better ending to my campaign experience. It was especially humbling to hear Win Butler constantly thank us for all the hard work we put into the campaign, telling us they were especially honored to have been asked to play this event. I will not bore you with the details of my life on the campaign, but suffice to say it has been the most memorable experience of my life. It's an experience that cannot be matched and we are reminded that we are in a sort of limbo everyday now that it's all over. As Win humorously remarked in the middle of the concert, "This is the funnest party I've been to for people who have all just lost their jobs".

By the time Jay-Z came on, I was mostly too busy having fun to remember I had a camera, so he's not in many pictures. Check out all of them, and Arcade Fire's setlist, below..."

Nguyen has been kind enough to let us reprint his photos of this once in a lifetime experience. Check out his vast folio and blog at www.baonguyenphoto.com. And then, set forth...
