John Maus is an American musician, composer, singer, and songwriter known for his baritone singing style and his use of vintage synthesizer sounds and Medieval church modes, a combination that often draws comparisons to 1980s goth-pop. His early lo-fi recordings anticipated and inspired the late 2000s hypnagogic pop movement. On stage, he is characterized for his intense displays of emotion while performing. He is also a former teacher of philosophy at the University of Hawaii, where he later earned his PhD in political science.

Hypnagogic pop is pop or psychedelic music that evokes cultural memory and nostalgia for the popular entertainment of the past. It emerged in the mid to late 2000s as American lo-fi and noise musicians began adopting retro aesthetics remembered from their childhood, such as radio rock, new wave pop, light rock, video game music, synth-pop, and R&B. Recordings circulated on cassette or Internet blogs and were typically marked by the use of outmoded analog equipment and DIY experimentation.
