This Sunday we are going deep... deep underground. We'll be exploring the vast networks of transport, data and urban infrastructure tunnels beneath the surface of the city, with a selection of sounds chosen for you by 4-D Traveller from such artists as Bochum Welt, Airlocktronics, Autechre, ADJ & Pathic, Ballet Mechanique, Aphex Twin, Aural Float, Synapse, Air Liquide and Boards Of Canada. Opening the hatch and climbing down below at 19:00 CET on The Dream Machine.
