Sundial is an ongoing project to document the 24-hour rhythm of cities. Bennett makes "time-lapse" sound recordings from a single point in a city during 24 hours. These are then edited to form a continuous piece of about 8 minutes, allowing the listener to hear the changes at an accelerated pace.
The recordings are made with a 'soundfield' microphone, allowing a 3D reproduction of the original soundscape, which adds to the immersive quality of the piece. The work is usually presented from a DVD, with titles showing the location and the changing time. The cities up to now include Paris, Brussels, Amsterdam, Istanbul, Guangzhou, Barcelona and Vienna.
