Extended until 11th July due to demand



You are invited to vocalise your inner frustrations and power a large-scale light installation. Join a Zoom call and watch your outburst illuminate a four storey office building.



With social distancing still in place and tensions continuing to rise, London-based artist Marcus Lyall has transformed a soon-to-be-demolished office block in London Bridge into an interactive public artwork.  In this new site-specific work, Lyall invites you to join a Zoom call where you can scream, yell, shout or otherwise vocalise your feelings.

A monumental light installation instantly illuminates the building in response to your voice. The louder and longer your outburst, the bigger the response from the building. The building interprets every voice and scream differently, to create a unique response for each guest.

You can participate using any device that supports the Zoom app. The artwork is designed as a safe and constructive excuse for people to release their inner tension. ‘Primal Scream therapy’ has long been investigated as beneficial for psychological issues such as depression and anxiety. While the artist makes no medical claims, a long and loud shout may be a good way to relieve inner tensions.


16th June - 11th July 2020

Opening hours for participating
Tuesday - Saturday  
8.30pm - 12.30am

Physical Address:
55 Southwark Street
London Bridge

The installation can be viewed from the street between 8.30pm-12.30am Tuesday - Saturday


Instructions for the optimum screaming experience on Zoom

1) One person can scream at a time. Sessions are limited to around 20 seconds. Bear with us admitting you to the call. 

2) Make sure your microphone is turned on and your sound settings are correct.

3) Make sure video is turned on and you have positioned yourself in the centre of your camera.

4) Zoom seems to dislike some people’s screams. If you have issues with the sound cutting out, try the following.

a) Go to ‘Settings’ in the Zoom app. 
b) Hit the ‘Audio’ icon. 
c) Hit the ‘Advanced’ box in the bottom right hand corner. 
d) Disable ‘Suppress Persistent Background Noise’ and ‘Suppress Intermittent Background Noise’

5) Please scream responsibly. If you think your neighbours might be concerned, let them now what you’re doing (and ask them if they want to try it)

6) The building responds to the volume, pitch and length of your outburst. The longer it is, the brighter the building will light up.

Submit your scream
If you cannot attend during opening hours, you can send a short video of yourself to  We will play all submissions on the building and post a Youtube link each day.



Tuesday - Saturday  
(8.30pm - 12.30am)


I developed the artwork to provide a cathartic release for people isolating at home, by providing a big colourful object to yell at - Under these extraordinary circumstances, vocal profanity is permitted.
— Marcus Lyall

All calls will be recorded for artistic purposes and may be used by the artist to develop future installations.

Marcus was heard discussing the project in a broadcast on Resonance FM on Sunday 21st June as part of Bankside Open Spaces Trusts - Great Get Together - this year due to current global situation instead of a live street party, they brought everyone together via radio with “The Power of Community” as its theme.
