Backstreet Boys perform in Cleveland, OH August 27, 2010. Thanks to cleveland.metromix.com for the photos.

I know everyone has been waiting for my pics from lastnight’s concert in Pittsburgh. I’ve added 69 photos and they are of all the guys. All that I ask is that you please do not upload them on any other site/gallery. You can post about them and put a link to Kaos Online. Do not take our tag off them or use them in graphics. You can save them if you want. Enjoy the pics.

If you’re going to the Backstreet Boys concert in Pittsburgh, PA tomorrow I’ll be there as well in front row section 103. I’ll take tons of pics and videos that I’ll be posting in the days after once I am able to go through all of them. Hope everyone that goes has a great time!

For now here’s the concert poster I had found. Thanks to Tino Coury at Facebook. Click to view full size at the gallery.
