..too, although there are pro's and con's to this, what's equally important-if not more important in the long run-is matching chemisty/personalities. It's a people biz., much like anything else. So it's important you share similar philosophies. Accordingly, my preference in auditions is about 1/3 doing the learned requested stuff and 2/3'rds just 'coming-up' with stuff like grooves and jamming or blues or whatever. Thru that process you'll discover real quick if you've got chemistry for the long-haul (or even short-haul).
I remember two bands I was in where the drummer's didn't even like to jam. It was wierd to me, and to this day I never really understood it. In both those instances...., they broke-up. So musicianship, philosophy, personality play a huge role in not only nurturing a so-called creative environment, but contribute greatly to the fun factor. Afterall, what are we in it for....(aka; ask yourself why you're auditioning in the first place) (?).
