Jantzen has sold work in galleries throughout Europe and the United States and has been presented at numerous international art fairs in London, Amsterdam, Singapore, New York, and Miami, his work can also be found in many renowned private and public collections around the world.

Jantzen is currently working and operating from his studios in Barcelona and New York, both hot spots of the contemporary art scene to stay abreast of the rapidly changing art world to keep his work innovative and fresh. His early works found pop inspired imagery creating new contexts from photo journalism and advertising with highly detailed enlarged objects placed out of their environment. Successive shows moved on to use and explore cinematic stills as the source of a visual collective consciousness incorporating the vocabulary of cinematography and the expediency of digital photography as an inspiration for the new art works.

In the latest body of work Nemo Jantzen goes beyond telling a one image story and depicting a voyeuristic look into another world and reality. His work carefully selecting hundreds of photographic images by color and theme, Nemo takes Neo-pointillism to the next level exploring the dialogue of narrative tropes in an image soaked contemporary environment and collective unconscious. A magical plethora of colors with hundreds of images depicting, stories, momentous, personal experiences and cinematographic scenes encapsulated in crystal spheres that together form large compositions and portraits reflecting an idealized world filtered through the demands of the eye of the beholder.
