Bloch has been interested in digital electronics since 1977 when he created his first computer-related artwork. His art uses the postal system as well as other communications media. In 1989, after over a decade working in mail art, he began to work on the Internet and soon after created a "digital performance artwork in progress" called Panscan for Echo Communications.
Bloch has done video, performance art and experimental music since the late 1970's and also works with networks, e-mail art, postcards, 'artistamps' , coded envelopes, information theory, mass media, speaking, journalism and broadcasting.
He became active with mail art in 1977 and created several international postal art, post-art games including the infamous Last Mail Art Show which created controversy. He also raises eyebrows by eschewing institutionalized anarchy such as Neoism and the IUOMA, prefering instead the strategies of Arthur Cravan. However, he supports the work of Neoists and other traffickers in Externality everywhere and is an advocate for artists' rights and against the mythic stereotype of the "starving artist." He adheres to principles originated with Situationism, DIY and other forms of Postmodernism in his theoretical approach to issues of art and commerce but refers to it in his writings as "Pan-Modern."
For the past 14 years, since embarking on his personal Art Strike, Bloch creates a new manifesto every day upon waking. These writings remain unpublished.
Bloch also creates articles, pamphlets, books, and mail art-related projects in the tradition of Johann Gutenberg, William Blake, William Morris, Thomas Paine, and El Lissitzky. He recently revived his irregularly issued fanzine called Panmag in the form of a cable TV in New York show called Panscan TV.
