An alternative but not necessarily parallel universe is forming in Southeast Portland this weekend. They call "Esozone: the other tomorrow" a festival, but don't expect corn dogs and Ferris wheels. Fringe thinkers, visionary artists and occult musicians from around the world will gather at Watershed, a rambling, ramshackle building near Sellwood for a weekend of ... well ... the inexplicable. Noah Mickens, who will take part in the festivities, defines it this way: "Esozone is an exhibition of scientists, philosophers, magicians and performance artists, gathered together by a subculture of young radicals who don't recognize the distinction between the four." Of course, you still may be a little fuzzy about exactly what goes on. You're not alone.
