In the summer 2016, Rowlett attended the Snow Pond Composers Workshop in Sidney, ME. A few weeks before the workshop, he

came down with a severe headache. The pain was throbbing and debilitating. Rowlett found himself struggling to speak as his words were slurred. He was taking to an emergency room with the fear of a stroke, though unusual for someone at his young age of 21. The diagnosis was a cluster headache. Rowlett was prescribed some medication for the headaches that were still to come. The headaches in all spanned a period of over a month, encompassing Rowlett's time at the workshop. Clusters is a piece that uses musical episodes to represent the tension and release of cluster headaches., inspired by Rowlett's struggles with cluster headaches.
