Depending on the gear you're using now, there could be different responses. I guess I would say use a multi camera set up, as there will probably be changing lights and stuff, and inevitably some footage from some cameras would be unusable because of over or under exposure. However if you only have camera, I would say do a lot of closeups of the band so you don't have interference from any surrounding lights.

Get your sound from the mixing board rather than trying to catch it the normal way. It'll be the cleanest you can get that way.

Multiple cameras as posted above. Beyond the lighting issues you want something to cut to once in awhile to keep the video from getting dull. You should have at a minimum one camera for master shots and a second for closeups and getting crowd shots and stuff.

I'd also consider getting some shots of the band before and after they go onstage. You may never use it but it gives you something to make it a bit more interesting. Who knows you might get great post-party stuff that you want to intercut with or something.

Watch The Last Waltz. Best concert ever filmed(unsurprisingly it was directed by Martin Scorcesi).

Breaks up the songs with personal interviews with the band. Will give you ideas for how a professional would set up shots. I will assume that you only have one camera, since you stated that this is a step up from using a camera phone, so you will need to either become extremely inventive with your camera set ups or you will need to find another camera so that you can always have 2 different angles. Otherwise, it will become extremely boring if you just have a long master shot of the entire stage

Editing will be the trickiest part. If anything, film some shots of band members playing, but not to where you can actually tell the exact music they are playing(shoot the guitarists from an angle that doens't allow you see how he's playing the guitar or just the drummers face or the singer from behind or while he is not singing). These shots will allow you to insert them in places during a song, even though they weren't actually filmed during that specific song, in places where you are switching the camera set up. This may mean that you have to have the band actually "act" for some scenes before or after the concert or film some songs this way, even though the song will not be put into the video because the footage of it would all be used for other songs.

Again, just make sure to not set up one camera and film from a static spot. This makes for very boring watching. Sorry for the long post but hopefull it is helpful.

I am doing a two camera setup. As you guys said one main shot and one for close ups. IAs you guys were saying before it would get boring really fast if I just had one monotonous shot the whole time. the problem that I am facing right now is trying to find another camera that has a good mic input. A lot of commercial camcorders don't have mic inputs anymore which is killing me because I need to find a relatively cheap one. Got any ideas? As well any other equipment I might need?

I wouldn't worry about a camera with a good mic input. Any crappy sound will work for syncing. You should capture the sound directly from the mixing board, either from their into a camera (only need one with a good mic input in that case) or directly onto a computer (don't need any real sound equipment then). I'd go with the second option, the laptop connected to the mixing boards.

Another thing you want to do is film more than one concert if possible. That way you have more options. The second concert you could set up your master shots from a different angle and choose different closeups and add variety. It might look like you have a lot more cameras.

RJ is right. But check out these threads for info on cameras with the essentials.
