I like how tangible everything is in coffee. With the clarinet you practice, practice, practice and rehearse, rehearse, rehearse. When you perform, you’re training essentially invisible muscles to manufacture a vibrating column of air. Coffee is tangible. I am actually able to change the brain chemistry of my customers. Making an espresso is a performance that lasts ninety seconds and then you’re done. You go on to the next performance. You may get applause or you may get boos, and then you move on.
