Music of Mind Control with Micah is a weekly radio program on WFMU that bills itself as an "exploration into the musical output of religious cults, new religious movements, and individuals of a spiritually inspired and divine nature." In between songs (most of which are very listenable) the host provides information about the different cults from around the world whose music is featured on the show.
WFMU has good smartphone apps that let you listen to all of their different weekly shows.
