Robotic bells

This is the Mk III robotic bell rig, designed to make it easier to take the bells to venues – earlier versions saw the bells inside a shed or scattered around a gallery, in dozens of separate boxes. Here, I’ve mounted them on an old shop fitting, salvaged by Vivien Angliss from a place in Bedfordshire that was closing down.

The Mk III bells had their first outing in the Malborough Theatre’s inaugural Steampunk night (Brighton – curated by Tarik Elmoutawakil). I’ve also taken them to the Gasworks Gallery, Vauxhall (for a Resonance FM night, curated by Ed Baxter) and to a Spacedog night at the Freebutt, Brighton. I’ve been using them quite a bit in my own compositions for bells, saw, theremin and vocals. But here’s a video of the bells playing a classic – it’s Troika, from Prokovief’s Lieutenant Kije. Over the next few weeks, I’ll endeavour to post more videos of the bells in action.

Technical notes

The bells are being percussed by servo-driven, spring-mounted beaters. These are controlled by a LynxMotion SSC-32 servo control board, which is receiving serial signals from Max/MSP.  As you can see, the springs make the beaters remarkably responsive – they can even tackle the odd semiquaver. See also the Mk I version of the bells, in Swinging London – my automaton show for the South Bank Overture Weekend.

Live theremin AV controller

The theremin AV controller enables me to scrub audio and video samples live, using the pitch and volume aerials of the theremin. I created this simple but highly unusual controller using Max/MSP + Jitter.

I perform with vocalist Jenny Angliss (and sometimes with guitarists Mike Blow and Ben Kypreos too), under the band name Spacedog. If you’ve been to a recent Spacedog gig, you’ve probably seen the theremin controller in action. Here’s a video of me using the device in a rehearsal. As you can see, I’m controlling the speed of audio and video clips with the pitch antenna. I can also control volume of the samples using the volume antenna.

The music in the video is Willow’s Song (Paul Giovanni), as featured in the British classic horror film The Wicker Man (1973). Here, it’s being mixed with a sample from Hammer classic The Devil Rides Out (1968), plus a 1950s parakeet training record. I’m controlling the hypnotic voice of actor Charles Gray. Jenny is on vocals and Ben on guitar. Mike, in the green teeshirt, is cueing up the various samples I’ve prepared, as the song progresses.

Apologies for the lame sound of the ‘straight’ theremin this video – you’re hearing the sound through the desk. We were monitoring live and the gallery was so reverberant, we had to ditch every hint of vibrato to avoid complete chaos.

This version of the Willow’s Song was first performed at Atters’ Other World, the Brighton Festival Fringe, June 2008, then our sell-out show at the Sanctuary. Here, you’re watching an excerpt from a live playthough of our set in the Blank Gallery, Brighton. Lighting conditions in the gallery prevented us from filming the projected video live, so keen-eyed observers might notice that we’ve added that after filming.
