There is a long and noble tradition of great critics who have also been composers. But Josh Kosman writes that he still has an innate distrust of the composer-critic. “The artistic marketplace is an adversarial arena—or at least a competitive one, like any marketplace—and that makes it a setting in which it’s important for the participants to be clear and consistent about their allegiances. A critic’s exclusive allegiance, I am convinced, should be to his or her fellow audience members. A composer, by contrast, has other allegiances entirely—to his or her own creative imperatives, to the larger community of artists, even in some cases to posterity.”
