Illustrious were asked to participate as sound artists in the BT Artbox project of 2012. The project saw over 40 British and international artists creating replicas of the original K6 telephone kiosk.
The boxes were distributed throughout London in areas including Royal Parks, Soho, Camden, the London Aquarium, and outside Big Ben throughout June and July.
Martyn Ware created an eerie sound installation that was concealed inside an opaque telephone box featuring the sounds of someone trying to escape.
The BTArtBoxes were later sold at auction to raise funds for Childline.
