Jamador, you must've been RIGHT behind me - I was on the outer rail, center. I have the heart suitcase tattooed in the middle/top of my back and short brown hair.
oh, and love your pics. What kind of camera do you have? What settings did you use?
I actually WAS very close to you. I remember seeing your tattoo and thinking that it was a great idea for one
The camera that I have is a Canon Powershot S5 IS. It is probably 2-3 years old now, and Canon has since released a newer model of it, the SX10 IS, that has an even longer zoom range. These two cameras are great for using at concerts because they are kind of "in-between" compact digital cameras and dSLRs. The lens is not detachable, so I have never had any trouble getting it into shows, but it is definitely larger than a regular carry-around camera (it won't fit into your pocket). I do have an expensive dSLR, but didn't want to risk bringing it to the concert, and the long zoom lens (12x, and the SX10 has 20x) and smaller size is desirable for these types of situations.
Regarding settings...the main benefit of this camera is the ability to control everything manually, rather than relying on the camera to do all of the decision making for how to get the "best" picture. What the camera thinks often isn't correct in a low-lit situation like a concert. If you have a camera that you can control things like the ISO, aperture, and shutter speed, I would definitely use one of the modes where you can be in charge of those things. For me personally, I stick to the Shutter Speed priority mode (called "Tv" on these Canons). Shutter speed will be the most important thing that you can control at concerts because the overall lighting is pretty dark, your hands can shake while trying to take pictures, and the members of the band are almost always moving. The combination of these three things is what makes many concert photos come out very blurry. In order to properly STOP the movement and capture blur-free images, you really probably can't get away with using a shutter speed of less than 1/60th of a second. Adjust your ISO to the point where that shutter speed produces a good looking picture. I always fiddle with the settings during the opening band, so I can get a feel for how to get the best pictures of the headliner. Most of the pictures that I took during the U2 set were taken in the Shutter Speed priority mode, with a shutter speed ranging from 1/60th-1/125th of a second, and at ISO 400. The one drawback of this particular Canon model is that using any ISO above 400 produces some pretty noisy photos.
And finally...practice, practice, practice! Take tons of photos at the shows, try out different settings/speeds/ISOs, and find what works for each situation. The trouble with cameras and photography is that there is no "be all, end all" solution for taking good photos. Every situation is different, and every camera has its pros and cons, so it just takes a bit of effort to learn what works best for you. Hopefully, this post has made sense
Let me know if you have any other questions...I'm a bit of a camera nerd! Glad you liked the photos!
Maybe you shouldn't have yelled at security and talked on a normal tone with them instead?
but I liked Muse, they rocked..they just don't hold a candle to U2. I've already berated like 4 people I know for saying Muse was better..yuck. 
But I absolutely loved every minute of the show and it was one of the best experiences of my life. I had been stale on my U2 loving, but I'm back full swing, listening to all the bootlegs I downloaded years ago and all the albums (over and over and over). Thanks to everyone in the inner circle who went as crazy as me!
