Mixing ‘The Message’

March 8, 2009

We’re so used now to the sound that Grandmaster Flash created in the early ’80s that it’s hard to remember how different – and innovative – it was when he and his music first appeared.

Like other black music innovators – Gil Scott-Heron comes to mind, and Charlie Parker, come to that – he’s had his problems with drugs. He’s touring again, with a new record, and so was interviewed by Andrew Purcell in the Guardian, to whom he explained how he evolved his sound, in an age before ubiquitous personal computers or digital sound. As the article reminds us, he was the first person to mix two records without losing the beat; the first DJ to use drum machine loops live; the first to scratch;  and the first to make a record entirely of samples.

His method required technology that didn’t exist. “I needed a way to have the platter continuously spinning while I’m moving the record back and forth,” he says. “I went to a fabric store. When I touched this hairy stuff – felt – I found it. I rubbed spray starch on both sides and ironed it until it became a stiff wafer. After that, I was able to stop time.” DJs have taken slipmats for granted ever since.

When he tried out his technique in public, the crowd stared as if he was mad. Flash, only a teenager, ran off stage, threw up, went home and cried for days. But he couldn’t stay away from his turntables for long. Soon he began searching for a bigger, louder system. “I went to junkyards, abandoned car lots. I asked supermarkets for the big jugs they put pig guts in, to make cabinets for my bass speakers.” He worked out that traffic light sensors made good tweeters.

At home he dismantled domestic electronics like hairdryers and  radios in search of the perfect sound. There’s also a great line about wearing out records as you scratch them:

I ask him how many copies of the Incredible Bongo Band’s Apache he has worn out, in half a lifetime of playing it for its drumbeat, since the earliest parties at the Black Door club in the South Bronx. “About 30,” he reckons. Really? That’s fewer than one a year. “Oh yeah, but I play it until it’s disgusting, because the deeper the cavern is, the more you can do with it. I play it until it sounds like eggs frying on a Sunday morning.”

Tucker’s sound mirrors

Tucker\'s sound mirrors - www.everyoneforever.com

Watching an old episode of BBC’s Coast on DVD I came across the story of Major WS Tucker and his sound mirrors, built in some numbers in the ’20s and early ’30s along the south coast as an early warning system of incoming enemy planes. They were relatively sophisticated parabolic reflectors, which concentrated the sound and also enabled direction to be estimated. They were rendered redundant by the development of radar, and Tucker, apparently, was retired early and instructed to dismantle the mirrors. He didn’t completely comply.

And in a strange way, he had the last laugh; the organisation developed by Tucker to manage and respond to the incoming information was taken over wholesale by the radar teams – a reminder that the social and management systems that are developed around technologies are as important as the technology itself.

A web search throws up a surprisingly detailed set of documents from different sources.
