George Metzger began publishing his cautionary fables of utopias, apocalypses, and climate upheavals in fanzines in 1966 and was soon appearing in such seminal underground publications as Yellow Dog and Gothic Blimp Works. His first solo comic book, Moondog (1969), established him as a true comix visionary. More issues of Moondog followed, and he launched Truckin', a series celebrating life on the road. In 1978, he published Mu: The Land That Never Was, his epic about the fate of a lost continent. He has contributed other tales of wonder and whimsey to numerous publications, including Heavy Metal. In 2016, Fantagraphics Books re-issued his pioneering graphic novel, Beyond Time and Again. He continues to write and draw from his home in British Columbia. Patrick Rosenkranz is widely acknowledged as one of the premiere scholars of the underground comix movement. His books include Rebel Visions (the most widely-heralded history of the era) and The Artist Himself: A Rand Holmes Retrospective. He lives in Portland, OR.
