In demonology, Ipos is an Earl and powerful Prince of Hell (a Duke to some authors) who has thirty-six legions of demons under his command. He knows and can reveal all things, past, present and future (only the future to some authors, and past and future to others). He can make men witty and valiant.

He is commonly depicted with the body of an angel with the head of a lion, the tail of a hare, and the feet of a goose, less frequently in the same shape but with the body of a lion, and rarely as a vulture.

Other spellings: Aiperos, Ayperos, Ayporos, Ipes.

John Zorn (born September 2, 1953 in New York City) is an American avant-garde composer, arranger, record producer, saxophonist and multi-instrumentalist. Zorn is a prolific artist: he has hundreds of album credits as performer, composer, or producer. He has had experience with a variety of genres including jazz, rock, hardcore punk, classical, extreme metal, klezmer, film, cartoon, popular, and improvised music. Zorn brings these styles to his work, which he refers to with the label avant-garde/experimental.

Zorn has stated: "All the various styles are organically connected to one another. I'm an additive person - the entire storehouse of my knowledge informs everything I do. People are so obsessed with the surface that they can't see the connections, but they are there."

Zorn has led the punk jazz band Naked City and the klezmer-influenced quartet Masada, composed Masada Songbooks (written concert music for classical ensembles), and has produced music for film and documentary.

Zorn established himself within the New York City downtown music movement in the mid 1970s and has since composed and performed with a wide range of musicians working in diverse musical areas. By the early 1990s Zorn was working extensively in Japan, attracted by that culture's openness about borrowing and remixing ingredients from elsewhere, before returning to New York as a permanent base in the mid-1990s. Zorn has undertaken many tours of Europe, Asia, and the Middle East, often performing at festivals with varying ensembles to display his diverse output.
