Power electronics was originally coined by William Bennett as part of the sleevenotes to the Whitehouse album Psychopathia Sexualis, and is related to the early Industrial Records scene but later became more identified with noise music. It consists of static, screeching waves of feedback, analogue synthesizers making sub-bass pulses or high frequency squealing sounds, and screamed, distorted, often hateful and offensive lyrics. Deeply atonal, there are no conventional melodies or rhythms.Tellus Audio Cassette Magazine produced a compilation compact cassette tape called Power Electronics in 1986 that was curated by Joseph Nechvatal.
