Hack Of The Night : How to get the best sound when recording at a concert

It's the worst when you go to a concert and take a video, then watch it back later and the audio is so over-amplified that you can't even understand it.  You could do what this hack says, but scroll below the picture to see how I would make this one even better....

Ok, that sounds good, but the problem with that is you always have to have your hand in the same spot so your thumb doesn't slip off the mic.  Instead, take a piece of tape and put that over the microphone.  That way it limits the sound that gets in, and when you listen to it back later, it'll be much clearer.  Give it a shot!
