Tiny Tractors Of Doom

I've spent half of today beneath the surface of London. I wasn't stuck on the tube, but pelting round cable tunnels on a minature tractor laden down with enough safety equipment to make a sane person slightly concerned. Mile upon mile of weird black metal* tunnels that ring inner London to keep STUFF working. I love workdays like that. The only problem was that we couldn't take photos, not even of the gear we were working on due to security issues, which was a real shame, cos there's some weird shit beneath yr feet that you'd never even guess was there. Very Quatermass it was, I kept listening for eldritch slitherings and bubblings, but apart from the odd drip of water(?) and the occasional scurrying of rats(??) I didn't hear much, nothing at all in fact. It was so damn quiet down there the lack of sound seemed like a physical thing as opposed to just its absence. Some of these tunnels must be the most silent places in London outside of an anechoic chamber. It's only when the ambient noise y're used to is so thoroughly absent that you realise how efficient yr brain is at filtering the stuff out. When we finally emerged London suddenly seemed so much louder than I'd ever experienced it before, so I went for a wander instead of eating lunch, just listening to the weird moving interplay of harmonics and phase that surrounds us all the time and we never notice. London is a fucking amazing piece of music, you just have to stop and really listen for a while...

*I know. Bad unintentional pun there. It was pretty necro tho.
