"Last month Jane Bennett gave a talk at New York’s New School entitled “Powers of the Hoard: Artistry and Agency in a World of Vibrant Matter”. She was interested in the question of whether or not compulsive hoarders have a particular affinity for matter, specifically, the matter of/in the things they so assiduously collect. The purpose of this post is to ask a similar question about trumpet players and their mouthpieces. Some have only a few, while others have hundreds."
