Hardcore... never would have guess that, not with your avatar of the powerpuff girls being de-eyed
Some VERY important things to keep in mind while doing your first show:
* Don't jump at/ on the first groupie you get... be patient, the better ones always come later!
* If you get nervous, remember what Bob Dylan and the lead singer from Tool did/ do, and just play with your back to the audience
* Charge for any autograph you sign that isn't written on a body part
* If opening for Whitesnake, don't let them use pyrotechnics
okay, seriously though...
* Video tape the show on a camcorder. When your band is done with the gig, you can watch the show and figure out any areas where you need to tighten stuff up, and also, stage presence can be worked out
* Never trust the house engineer! In my experience anyway, the house's (venue's) sound engineer always sucks. If you can find a sound engineer whose willing to work with you for free (or beer, next best thing), it'll help
