Intrigued by the false hillock at Arnold Circus, on Shoreditch’s Boundary Estate, artist Thor McIntyre-Burnie sent a microphone probe down into the soil and created a site-specific sound installation called Rubble Music https://vimeo.com/16022911
On the recording, sadly there were no voices of Old Nichol children playing, nor the music of a barrel organ, nor the whelk vendor’s cry, nor any other 19th-century cockney soundscape. But the trains rumbling out of Liverpool Street appeared to be over-represented.
The image above shows the Estate, and its central mount, under construction in the mid-1890s; the view is looking east towards St Philip’s Church, halfway up Mount Street (today’s Swanfield Street). The picture is part of a collection held at the London Metropolitan Archives, shelfmark 28.75 BOU.

Below: the Old Nichol, left, and the Estate, right, that was built upon its site. St Philip’s is on the right-hand edge of both maps.
