1. Don't Be An Idiot
There are a lot of bands, that I know, that when they made a demo or an album and started to get some positive vibes from different people (myspace, forums, comments after their live performance ect.), that they started to behave like complete f****** idiots. You should see these people before they get on stage; if there are playing in the middle of a, lets say 5 band set, they are the guys that are mostly at the back of the show, or are hanging by at the beer stand and constantly commenting on how every band sucks (the guitar player missed 15 notes, the bass player sucks, the drummer doesn't know how to play the double kick pedal ect.)... After their show they are the ones that will tell you how they could have done better if they had the right vibe, or some other excuse so they can cover up that their playing sucks and of course... they will usually give you a high 5 after you are done playing with your band and say that you kick ass, but as soon as you have walked away they will start saying s*** about you or/and your band...
Tip: Don't be one of those guys...music is about having fun, not about who has a bigger d***. You cannot buy respect, you earn it. Prior to a show, took the time to speak with other bands that are playing that night, maby you'll make some new friends, new gig contacts or just have a blast because someone has a bottle of whiskey... Be humble and salute every criticism that you will eventually get. It will be a reference point on where to go with your live playing and to work on your self and primarily on your band. Also, if someone says that you were great after a show, that doesn't mean that ESP/Pearl/Shure/Krank ect. will be knocking on your door anytime soon... be gratefull for every positive comment you get and again, soak up those comments and if they continue coming that means that you are doing something right. Mental note: DON'T CONSTANTLY TALK S*** ABOUT OTHER BANDS! You'll just get labeled as a band that talks s*** about other bands and will be on the black list of promotors, bands, venues ect.
2. Time Is Money
There were some situations when I was doing a previously noted 5 band metal night and when there are 5 bands that are eagerly itching to get on stage things start to get hectic. Every venue (yes, even smaller ones) has a schedule and no one likes bands that are we are metal gods and no one tells us when to start or stop playing... reality check; you're idiots. On numerous occasions I saw bands that were playing 15min longer that they were allowed to and let me tell you...they never played in that venue again. The thing that pisses me off is that when there is a change up between bands (let's say you're playing a 30min set and then comes the 15min interlude where you need to get you're s*** and get the f*** off stage, and in that short time the next band has to plug in, tune, arange the drums ect) that people get nervous and you hear a lot of words involving mothers, sisters, fathers and holes... Most people think that the world revolves around their band and that they deserve being in the spotlight all night... that ain't real.
Tip: You are not Metallica, you do not exceed your playing time just because you think that that's cool. Show that you're capable of playing in the desired time limit and get your stuff off the stage in the shortest time possible. Line up a couple of shows like that and you'll get a reputation of a band that's dead on with their playing time. If the crowd want's an encore you need to ask the promotor of the show if it's ok (it takes 10sec to do that via microphone and you'll see if he aproves or dissaproves). If it's ok, play one more song (no, not a 10min song) and if it isn't ok, say thanks to the crowd and get off the stage. Don't be difficult to work with and you'll be fine.
3. Live Playing Frenzy
Well let's see... playing live... now, a lot of bands think that playing live is a piece of cake. You can see bands playin live and sounding like someone is rapeing your ears. Playing live is a thing that's taken for granted by a lot of players/bands. Often you'll hear a kick ass demo only to see the band live and stood dumbfounded with a wtf? expression on your face. The problem is that some bands aren't taking rehersal serious and when the time comes to play live they often find themselfs pissed off as how their perfomance sucked and how the crowd...well, you know... Also, I really hate seeing bands that are like Dream Theatre on stage, you know, they have a 20cm radius in wich they can express themself, in short terms: THEY DON'T MOVE (yes, I like DT but hate their live performances). You know those bands that play some brutal/technical/groove ect. metal and when they play live they stand like they are frozen in time? Well, I know a couple... also, don't drink your ass off, if you heard that Slash could play while having a bottle of JD, that doesn't mean that you can. Chances are that you will throw up while playing and make an idiot out of yourself.
Tip: No one is going to eat your soul if you mess up while playing live, just loosen up. Have ONE beer before you go on and everything will bee ok, you don't become a professional over night. Also, rehearse, rehearse, rehearse... if you can play any part of your songs in 2 a.m. completely wasted, on drugs, with only one of your limbs working you'll do fine on stage. And try to move bit, bang your head, walk here and there...and remeber, it's not about you, it's about the music and the feel of playing live.
