Field recordist Christopher DeLaurenti has composed a new audio collage based on footage of protest. Described by the artist as a sonic meditation, the piece uses social media feeds taken from the Missouri protests of 2014 following the fatal shooting of Michael Brown by a police officer in Ferguson. Titled Fit The Description: Ferguson 9–13, August 2014, it incorporates sounds from video feeds, Tweets, Instagrams and Vines from the day of Brown’s death on 9 August and the subsequent nights that followed.

DeLaurenti wrote an online column for The Wire in April 2014 on sonic protests and the process of field recording social change. Talking about Fit The Description, he explains: “While many radio and television reports packaged the subsequent events in Ferguson with a near-pornographic fixation on looting and property damage, sceptical viewers and listeners had to go online and piece together a mosaic of video feeds and social media reports to get a sense of what people there were thinking, feeling, saying, and doing.”

Fit The Description was commissioned by the Creative Audio Unit of Australia’s Radio National for the audio arts show Soundproof. You can hear it on DeLaurenti's Soundcloud.

Lewisham Arthouse will host the first in a new series of events at the Albany Theatre in South East London. Called Sound Is Sound Is Sound, it aims to highlight the varied nature of DIY music within London's SE postcode.

Programmed to run every six months, this first edition takes place on 24 October, with a live performance from Albert Newton, a longterm project currently consisting of John Edwards, Pat Thomas and Charles Hayward. Other confirmed artists include Aine O'Dwyer, the Norwegian electro pop duo Soft As Snow and the electronic trio The Balloons. Other events include a workshop with TV and film soundtrack composers John Lunn (Downton Abbey) and Frank Byng (The Mill), Charles Hayward presenting a workshop/performance called The Bell Agency, described as "a simple and focused game structure that explores the possibilities of improvisation outside of genre and technique", as well as installations and interventions running throughout the day.
