muzan-e - a subset of Japanese ukiyo-e, depicting violence and other atrocities.
Mauro, a self-taught manga artist from Japan, has a fascination with deformities, 'circus freaks', birth defects and human oddities and his work has a cult following around the globe. Because many of his illustrations depict graphic sex and violence, his work is often deemed too graphic for many popular Japanese manga publications. Mauro is often considered one of the greatest retro-artists working in the manga field today.
Mauro's illustrations have been featured in the liner art of jazz legend John Zorn's 'Naked City' albums. His book, 'Mr. Arashi's Amazing Freak Show', has been adapted into an animated film, but has received little release. His work is often referred to as 'erotic-grotesque'.
