Dan Graham is among the most influential of the Conceptual artists who emerged in America during the mid 1960s. A pioneer in performance and video art in the 1970s, Graham later turned his attention to architectural projects designed for social interaction in public spaces, among them The Children´s Pavilion with Jeff Wall. Writing has always been a major aspect of Graham´s work. His texts range from early Conceptual art pieces inserted in mass-market magazines, to writing on his fellow artists, to analyses of popular culture from Dean Martin to the post-Punk era. Well-known also among architects and urban theorists, during the 1990s Graham has been offered major public commissions throughout North America and Europe. The artist has chosen an extract from the science fiction novel ´Ubik´ by Philip K Dick, whose writings were a formative influence. A substantial Artist´s Writings section, key to understanding Dan Graham, completes the book.
