Elizabeth Clare Prophet's "Mass Against Rock Music" comprises recordings that document Prophet's spiritual campaign against the negative influences of rock music. These masses were hypnotic drone chants aimed at promoting spiritual protection and purity.

Prophet claimed to be a messenger of spiritual hierarchy known as the Ascended Masters, who she asserted communicated with her and through her. The teachings covered topics such as karma, reincarnation, and spiritual enlightenment, taking inspiration from various religious and spiritual traditions. Elizabeth Clare Prophet made numerous predictions about apocalyptic events, including the end of the world, which, surprisingly, did not come to pass.
