There is a group from somewhere on the eastern US seaboard who do tracklaying work songs. These are accompanied by the sound of hammers bashing rails into place. They toured the UK last year, bringing a set of sledgehammers and yards of steel rail with them. (I missed hearing them).

The most industrial thing I've ever heard was a performance by the Glasgow experimental-arts group Test Department in the early 90s. It was held in an abandoned locomotive factory that still had much of the original equipment in place. At one point there was a group of about a dozen people doing Stalinist-style callisthenics on a moving locomotive transporter (just visible through the smoke and flares) with a percussion ensemble of assorted metallophones, with the equivalent of the large gong in a gamelan ensemble being a suspended mixer bucket from a full-size premixed-concrete truck, whacked with six feet of railway line suspended from a chain. There was so much going on you could hardly hear it. There were several megalomanic shows like that in Glasgow around that time, I miss that stuff.

Nobody's mentioned the lagerphone yet.
