In addition, Dr. Joe Stuessy, a music professor at the University of Texas at San Antonio, spoke regarding the power of music to influence behavior. He argued that heavy metal was different from earlier forms of music such as jazz and rock and roll because it was "church music" and "had as one of its central elements the element of hatred." Dr. Paul King, a child and adolescent psychiatrist, testified on the deification of heavy metal musicians, and to the presentation of heavy metal as a religion. He also stated that "many" adolescents read deeply into song lyrics.
