Duncan donned a disguise and fired a blank-loaded pistol at point-blank range at two carefully selected participants, Tom Recchion and Paul McCarthy, chosen “...because they were close friends who would not expect anything like this to happen to them and who would be able to appreciate the event as I intended it”.

[4] Blind Date, involving intercourse with a female corpse followed by a vasectomy, both conducted in private, was presented as an audio-only event to an audience in a darkened warehouse, a demonstration of how men are conditioned to turn emotional suffering into rage.

The performance For Women Only is centered around a film intended to erotically arouse the all-woman audience, who were then invited to enter a back room and abuse Duncan sexually.

The collage series that he produced for display in strategically selected public men's toilets called The Toilet Exhibition combined graphic war-damage images from world events with commercial pornography to emphasize links between them, in private stalls frequented by men from government offices (Kokkai-gijidomae), the banking sector (Hibia) and the fashion industry (Shibuya), at moments of absentminded contemplation.

He also directed a series of commercial adult videos for Kuki Inc. under the name John See, for which he also wrote the scripts, edited, composed soundtracks and occasionally acted in incidental roles.

The Maze event in June 1995 involved a group of seven volunteer participants, including Duncan and an infant child, locked naked and blind overnight in an Amsterdam cellar in order to directly experience workings of the mind in a situation of unexpected sensory deprivation.

In autumn 1996 they left Amsterdam and set up a studio in Scrutto di San Leonardo, a village of fewer than 100 inhabitants in the Friuli-Venezia-Giulia province of Italy at the border with Slovenia.

Art works from this period include the outdoor audio installation The Keening Towers (2003) for the 2nd Gothenburg Biennial composed with children's voices, played continuously for 90 days over speakers suspended 25 meters above the entrance to the Gothenburg Art Museum, as well as the performance event Voice Contact (1998–2000) where volunteer participants enter alone, nude and blind into an empty room as Duncan, also nude and blind, responds uniquely to each according to their movements within the space.

The Error was first included together with a DVD video version of the work in Dialogue 1 at Gallery Enrico Fornello in Prato, Italy, curated in 2006 by Simone Menegoi.

Copies of The Error are in the collections of Niklas Belenius, Leif Elggren, Piergiorgio Fornello, Paul McCarthy, Giuliana Stefani and François Kaeser, who sponsored the production.

[15] In 2006 he recorded Our Telluric Conversation with Carl Michael von Hausswolff and Nine Suggestions with Pan Sonic members Mika Vainio and Ilpo Väisänen.

The audio installation The Garden with Valerio Tricoli was included in the 2006 edition of Eco e Narciso held at the IPCA Ecomuseum [16] in the province of Turin, a deserted factory complex once infamous for production methods that directly caused the deaths of several thousand workers as well as hundreds of residents of the surrounding area.

In September, Duncan curated Cross Lake Atlantic with large-scale works by Scott Arford, Gary Jo Gardenhire, Kim Gordon and Jutta Koether, Brandon LaBelle, Teresa Margolles and Fredrik Nilsen at Gallery Enrico Fornello in Prato.

[18] In February 2008 Duncan's audio installation The Gauntlet was held at Färgfabriken[19] in Stockholm: a series of anti-theft alarms with infrared sensors, turned on at ten-minute intervals and triggered at random by visitors moving blindly through the darkened hall.

In June 2008 Ensemble Phoenix performed interpretations with acoustic instruments of Phantom Broadcast, scored and conducted by Duncan, in live concerts held at Gare du Nord in Basel and Dampfzentrale in Bern.

In May 2009 Ensemble Phoenix performed a modified interpretation of Phantom Broadcast in a live concert again conducted by Duncan, held at Teatro San Leonardo in Bologna for the Angelica 2009 Festival.

In June, Duncan and Pasut performed an early version of their dance duet An Open Area Inside the Mountain at Teatro Dimora in Mondaino, Italy.

von Hausswolff performed Nocturnal Denizens in a concert for the Cut & Splice festival sponsored by the BBC held at Wilton's Music Hall, London.
