A passionately argued and intensively researched addition to the ever-evolving narrative of UK dance music culture. The history of dance music has been hugely mythologised. Were there any particular cliches you wanted to avoid?

You are correct that these are party lines. The letters represent an additional digit dialed after the others in cases where automatic operations was implemented. This article goes into great depth all about how multi-party telephone lines worked, but as a short excerpt:

Nevertheless, Party Lines ends on optimism – the founding spirit of the dance floor, after all. Gillett believes that we don’t need another revolutionary moment like the rave at Castlemorton, but rather “a patchwork of tiny gestures, each of them committed to serving a specific community, each small enough to evade censure, but… knitting together to form something of immense power.” Things, surely, can only get better.

Ed Gillett: Dance music is desirable, it’s alluring, it has a cultural cachet, and I think it’s been very easy for successive generations to mistake that for genuine community. So there’s a risk of dance music becoming tokenistic in its politics. You get quite a lot of shallow, superficial feel-good semi-political activity and there isn’t always the space to have deeper conversations. There’s one festival (I won’t single them out) who were lauded in the press for having a 50/50 gender balance on its bill. That’s good in and of itself, but the festival is run by this huge corporate entity – it’s the same old white men. Around the same time, party lines hooked up to computer modems and people could type to each other as well as talk. The technology’s popularity allowed a brief resurgence. One party line hosted a wedding, where the bride, groom, and officiant were at different terminals in Manhattan. Instead of throwing rice, the 1,000 callers who tuned in typed apostrophes. “It was very beautiful,” said a party line owner, “and very profitable.” One thing I found striking about the book is that it partly functions as a history of policing across the last four decades. What role has the police played in the history of dance music?

The dial was a mechanical interrupter so the marks and spaces were the same length, as I remember it. This worked but was slow and eventually was replaced starting in 1961 by an electronic 2-tone system.

Sorry, this event is now cancelled.

I got on at 1 in the morning, and I didn’t get off till 6 in the morning,” one girl said on Connections, according to the Tribune. Ed Gillett: In the book I talk about AI and climate change. The threats posed by AI to dance music are the same as with any other cultural pursuit. I guess the interpersonal nature of DJ’ing and the experience of being in a club might help certain sections hold out for longer. But we’re not far from the point that AI will be able to mimic basically any genre. Dance music is synthetic by its nature, it’s designed to be functional and often quite minimal in the elements it uses – there are very few fields of endeavour more suited to AI.

Change the plan you will roll onto at any time during your trial by visiting the “Settings & Account” section. What happens at the end of my trial? With regard to automatic operation, in metropolitan areas, the dials had most of the letters of the alphabet associated with digit values, and through that scheme J, M, R and W were associated with the digits 5, 6, 7, and 9. In other areas, when the dials did not have the full repertoire of letters, they nevertheless had J, M, R and W on the corresponding digits. It is quite correct to say this was done to make it easier for the human (mostly women by this time) operator. Transylvania-6 and -7 were NYC exchanges the most famous number was Transylvania-6-5000 used in the song by that name. (See note below.) That was before my time, but I remember it was the Hotel Pennsylvania near Madison Square Garden. (Its still there!) I don't think this has much to do with the Morse code. The letter is the same as dialing the number. Look on your dial the numbers are still there. Later when the telephone number system was expanded, my number in NJ was through the Charter exchange; Ch-9-0979. C is 2 and H is 4. So you actually dialed 24-9-0979.

Dancing to music: what could be more joyful? Rhythm and sweat, release and abandon, feeling rather than thinking, being yourself and becoming someone – or something – other. Dancing gives us, however fleeting, a glimpse of freedom. It can tilt reality. This appalls puritans and fundamentalists. Too many young people “prefer the dark night to daylight”, complained James Anderton in the 1980s. “They dance like there is no tomorrow, and they spread the virus of drug abuse wherever they go. They are not of this world. They believe in very different things to you and I.” In 1971/72, I lived in a grotty flat on Westbourne Park Road, a couple of streets away from Island’s studios. We bought out veg on Portobello Road, saw films at the Electric Cinema, but rarely ventured further west to Ladbroke Grove or north past the motorway overpass to the nether reaches of the market. For a short while I sold Frendz on the streets - I was very bad at it - but that involved going to the office which was up that way. I recall seeing completely burnt-out saucepans for sale on a market stall, which puzzled me. All of which is to say that we didn’t have really any interaction with the West Indian community and I don’t recall any obvious presence on their part. The place was crammed with hippies and boarded up rows of houses, but squatting was not yet widespread, although there was talk of it.
