Band Getups and Costumes
One thing you will notice about bands today is that they use various things to get noticed. Some would sport outrageous hairdo while others would wear strange wardrobe outfits to go with their music. One thing about bands is you cannot enforce being conservative. Their appearance is in line with what type of music they are rendering.
That is just how general bands should be. It is not a matter of rendering good music to the folks. You have to create identity and wardrobe and representation are simply part of it so don’t be surprised.
