Sounds of the square

As the shops started to close and the street-food vendors began to disperse, twilight was falling on Deptford High Street. Arriving an hour early for last night’s concert by Mike Westbrook’s Uncommon Orchestra at the Albany Theatre, I heard a strange sound and walked towards it.

It was coming from half a dozen identical large tubular silver metal structures erected in Giffin Square, each of them a tripod about 15ft tall, all topped with horizontal arms that ended in a speaker horn at both ends. The arms rotated gently, like the horns in a Hammond B3’s Leslie speaker cabinet, while emitting soft sustained sounds that, in combination, made me think of Terry Riley’s all-night organ concerts of the 1970s and of Brian Eno’s Bloom, the generative-music software he invented a few years ago to turn your iPhone into a self-activating musical instrument.

Just my kind of thing, in fact, and even more so when the accumulated layers grew into the sort of sound you might expect if you made a loop of the bells of every village church in Tuscany and then re-recorded the results under water. You could wander between the metal structures, and many people did. As the last of the daylight faded, the little red lights on each horn glowed more distinctly, and the sound took on a magical quality.

This, it turned out, was Chorus, a piece by the award-winning sound artist and composer Ray Lee, who specialises in such installations. In its full iteration, Chorus features 14 of the tripods, but six was fine for the intimate space of Giffin Square. The piece had its premiere in Newbury in 2013 and has since been heard in many places, including WOMAD and festivals in Warsaw and Melbourne. I wish Lee would come and park it in my street for a week or two.

* Chorus is on again in Gifford Square, Deptford tomorrow (Saturday, September 30) at 1.30pm, 2.30pm and 3.30pm.
