How will urban, ultra-wired Net artists Jennifer and Kevin McCoy (creators of the online work "Airworld") create a site-specific, two-day project relating to a sleepy one-street village in New York State? Mark your calendars for July 28-29. That's when the duo will join a group of 30 emerging contemporary artists invited to interface with the tiny community of Brewster, New York and devise original works of art inspired by the folksy locale. The public's invited to see what they come up with.
