Beech St. Tunnel - Immersive Audio Visual Space

The City, in the form of the Barbican Arts Centre, have applied to, er, the City, for a license to convert the Beech St Tunnel into an "Immersive Audio Visual Space" in which they plan have lighting systems and a PA system too.

The performance/event will happen on Fri 16th - Sun 18th March 2018, but I think this excludes the time needed to set up and tear down the installation.

You can make representations to the City regarding this license application up to the 24th December. Send your comments to licensing@cityoflondon.gov.uk​​​​​.
Here is how the event is described in the license application:
