What is Roam? Well, picture a mobile village green preservation society, wending its way across London’s five host boroughs for London 2012, stopping off to lead foraging walks or geology talks. Think of it as a very British version of Ken Kesey’s magic bus – a TARDIS on wheels – an old library van filled with ephemera, flora and fauna collected from the markets and charity shops it pulls up outside. It’s a place to hang out and daydream, where the daily guest speakers are well-versed in radical thought and untapped local knowledge. Imagine a versatile space filled with field recordings and site-specific sound installations, that packs itself up at the end of the day and drives off into the sunset.

This July, the Bank of America Merrill Lynch CREATE Art Award-winning project Roam starts its journey from Waltham Forest to Greenwich. Taking place in a specially reconstructed multi-purpose vehicle, Roam can be a gig venue, a lecture theatre, a nature disco, a reading room or a meeting point, depending where it stops. Sometimes it’ll be all of them in one day.
