Now, I'm not the kind of person who holds personal grudges- people make mistakes, life goes on, etc. On a professional level, however, there are some things people just shouldn't do. I'm not going to go into any specifics (yeah, right), rather, I will just list a few things I have gleaned within the past few days that I believe everybody can benefit from. 1.) Do not drink before a show. 2.) When the promoter/booking agent that set up the show (with you as the headlining band, no less!) is introducing you, do not be rude to them, take the microphone away from them, or demand that beer must be served to you before you might serve whatever function you do in that particular band. 3.) If a band member screws up during a show, just keep going. Do not glower, glare, give the evil eye, or stare at the person with the hate of a thousand sums if they miss a drum fill. This is highly unprofessional. Doing something even MORE stupid, like repremanding that person over the microphone, is so utterly un-professional, one would think I wouldn't have to warn others about it. 4.) Do not drink before the show. Not even one. 5.) Never deprecate the band or apologize for the performance. Saying things like "Sorry we suck tonight" or "wow, we really bleeped up that song" or "our drummer is playing everything too fast" is unacceptable. (Neither is slurring it.) 6.) Do not drink before the show. You might fall into the drum kit. Now, I'm not saying this in a bitter rant against any one in my band, but here's a few things that might happen as a result of these things: You will be embarassed in front of your fans, friends, peers, and professional contacts. You could get cut off in the middle of your set. You could very well impact the amount of money that you get paid. Moral of the story? Do not get loaded before playing a show, especially if you plan on taking your band seriously. Consider that there are others in your band, and that a stupid mistake can be costly for all parties involved.
