At the beginning of the “Power” episode, Damon Krukowski asserts, “the marginal-the rejected-the repressed-is whatever the powerful have decided is of no use at the moment.” He goes on to ask, “But might it [the marginal-the rejected-the repressed] not be a key to alternate approaches-to art, to society-to power itself?” (“Marginalized” is an adjective that describes a person, group, or concept that is treated as insignificant or peripheral.)  What is he trying to get at with this question? How does music indicate the differences between the powerful and the marginalized?
