It is helpful to consider the question of why practice everyday, and why work so hard on technique and hand speed and dexterity? The answer is pretty simple. When the performance arrives, as a drumset artist you do not want to spend energy or time or concentration on how your hands and feet are going to work together. All those practice hours train your hands what to do.
All that training gives the performer freedom to simply be creative on the drumset and have a more effective communication with the audience. Any time spent thinking about how your hands work during a show is robbing the audience of something potential magical, which is the connection between performer and audience.
