Head Phones President is a nu-metal group with abrasive, unrelenting female vocals. It was an unexpected turn for vocalist Anza Oyama, who was previously Tsukino Usagi in the Sailor Moon Musicals, as well as a part of idol group Sakurakko Club. Apparently somewhere along the line she went insane with rage, and thus Head Phones President was born. Now she screams about delicate issues such as prejudice.
