 In 
          1967 the Harrow based Ad Rhythm Records put out its first three 7 inch 
          singles, entitled Add Rhythm. Rather than featuring complete songs, 
          each of them contained four drum rhythms; two on each side for musicians 
          to "Add Rhythm to your own melody". The three singles, entitled 
          Dance Time, Pop Time and Latin Time, are a unique example of technological 
          repurposing; it was no longer your gramophone it was now, "the 
          most effective practice aid a musician ever had".

        Ad Rhythm Records never put out any further Add Rhythm 
          7 inches. And for the rest of their career, which lasted until about 
          1975, they concentrated on popular albums, largely composed using electric 
          organs of various types, and some of the exciting new synthesizers that 
          were starting to appear at the time.
        In August 2013, I found two of the Add Rhythm 7 inches 
          in a Red Cross charity shop in Hendon. Charity shopping is often a form 
          of media archaeology. Over the years in this same shop I have found 
          artifacts as disparate as a hand-painted Balinese divination calendar 
          and Deutsche Grammophon's eight DVD set of Wagner's Ring cycle.
         Taking 
          the Add Rhythm singles home two things became apparent: firstly that 
          these rhythms were entirely usable, and secondly that they represented 
          ancestral missing links in the technologies of break beats and sampling. 
          I resolved to use them for my own recordings, but then as I showed off 
          my newly won treasures online, I had a bigger idea: I thought that it 
          would be better if *lots* of people used them for recording.

          would be better if *lots* of people used them for recording.
        I set up an event on Facebook and invited every musician 
          I know, and they invited a few themselves. It was an opportunity to 
          fool the shopping mall of the latter-day internet into doing something 
          creative. Something more collaborative, obsessional and fetishistic. 
          Something more like the sort of thing that the internet used to be so 
          good at.
        I was slightly surprised at the enthusiasm of the 
          response. After all, what I was asking these musicians was to record 
          completely original, exclusive tracks, with strict limitations on the 
          form, and with no opportunity to make any money out of the process. 
        
        In total there were thirty-nine applicants. I digitised 
          all of the rhythms, initially at the intended 45rpm and then at 33rpm, 
          to give a total of sixteen rhythms, and then put them up onto Archive.org. 
          I chose a rhythm for each applicant, using a weighted stochastic distribution 
          which I like to call the Krishna Tombola System, and sent instructions 
          and a deadline:
      
       
        Most of the rhythms are a little under three minutes 
          in length at 45rpm, and extend to something like a minute and a half 
          at 33rpm. Each rhythm is introduced by a lead-in beat on a wood block 
          and some vinyl crackle. In many cases the artists left the vinyl crackle 
          intact and in one case even resampled and exaggerated it.
        By the 30th September I had received twenty-seven 
          recordings from the contributors. Over two thirds of the original applications. 
          I was astounded both by the quality and the range of material on these 
          recordings. Certainly I expected some of the playful noise-based reactions 
          to the rhythms but there were a wide range of musical responses using 
          a variety of techniques and even a pleasing array of songs. With most 
          tracks ranging between three to three and a half minutes, the resultant 
          feast is more like a mouthwatering selection of tapas than a stodgy 
          diet of carbohydrates.
        In summary, I'd like to thank all of the contributors 
          for their hard work and their enthusiasm for this project which has 
          turned a late 60s folly into a living musical chimaera. Whatever ambitions 
          the anonymous drummer and the studio technicians at Ad Rhythm records 
          might have had for their product, it is unlikely that they imagined 
          that over forty years in the future their work would be interpreted 
          in such a variety of colourful forms.
