I'm just havin' fun with the drum.
But my brother was a really good drummer and spent many hours a day, for many years, practicing his craft. He was proud of being one of the best time keepers around. If you screwed up, continually, or didn't know your part, it hurt his feelings and he would, in turn, hurt yours. You see, when you do your part, and all the others on the stage do theirs, majik happens, musical majik and that is what I love about music. You can, under the right circumstances, make majik happen. But, if someone is not on their game or knows not what they are even doing, it can ruin the whole session. So, think about this as you practice or audition. If you can't deal with the others, don't take the gig, you will be blamed by the others because you are "the new guy". And anytime you audition someone new guy, give him/her a few days to get to know your expectations. It will make a world of difference. Send tapes/zip drives/CDs, whatever so the new person knows what is expected. If they can't keep up after a week of listening to your stuff and on the third or fourth try at practice, a well placed drum stick to the solar plexus usually will get someone's attention. Maybe they get it, maybe they don't, but at least someone get's "the point".
