Travelling from home to work by underground constitutes an everyday 'in-between' experience that we're exploring through a project called undersound.

undersound is a new type of experience, an interface that is on your mobile phone and in the underground stations you pass through every day. It is part personal, part public and all about the tube. undersound is a way of listening to, distributing and affecting the flow of music in the underground that goes beyond just the music itself. It allows you to see your journeys, the people around you, and the tube itself in a new light.
