The advice I would like doesn't really matter because I will take any advice. We will have a chance to do a sound check and adjust levels thank god otherwise I would just roll in our PA (my friends) which is actually better than the one we will be using. I have only sang for one day into the mic but it was a long practice session of 4 hours yesterday and I realize singing in a mic is different than just singing. lol.. It's an art I am getting better at. Yesterday we sounded outstandingly awesome... Keep posting advice guys!
First of all, if you've only been singing for two weeks and are already sounding "outstandingly awesome," then I hate you! I've been singing for over 10 years, and I still don't think I sound even awesome most of the time, much less outstandingly so.
And yes, singing into a mic is much different from singing without one!
Anyway, now that that's out of the way, here's some advice.
1. Make a list of
everything you need to bring (guitar, cables, batteries, tuner, change for a parking meter?, etc.), and pack it all up, checking off each thing. Give yourself time to gather everything in a relaxed manner so you don't forget something stupid (like your guitar).
2. Get there early and allow yourself plenty of time to relax, breathe, settle down, and set up.
3. Don't be surprised in you can't move your leg or something once you start your set.
4. More than anything, remember to take some time, even if it's just 30 seconds or so, to concentrate on breathing deeply and relaxing. You'd be amazed how well this works. Concentrate on releasing your tension and remembering that you're there to have fun.
This is all under the assumption that you've adequately prepared for the gig. And if you haven't really done that, it's too late at this point!
Good luck
