John Maus (born February 23, 1980) is an American avant-garde musician, and composer. A keyboard player for Panda Bear and Ariel Pink, he has released three albums of his own music to acclaim. He grew up in Minnesota. He is known for his eclectic samples when composing, "an almost absurd mix – a stand-off between taut, bass-driven post-punk, whooshing electro-pop and, thanks to the chants and bleak intoning, Medieval and Gregorian disco."
